Provide optional file:stream pathname access\n through streams_interface\u003dwindows, exposing streams as regular file\n descriptors with support for mmap, locking, truncation, and\n allocation.\n\n - Support file attribute queries and updates through FS_IOC_GETFLAGS\n and FS_IOC_SETFLAGS. Store immutable, append-only, nodump, and\n noatime settings in the private $LINUXFLAGS extended attribute and\n restore them when loading inodes. Also report compression,\n encryption, and the mount-wide case-folding policy as read-only\n attributes.\n\n Other changes:\n\n - Expose the existing NTFS volume serial number through FS_IOC_GETFSUUID\n by registering it as an eight-byte filesystem identifier.\n\n - Validate MFT I/O geometry and write MFT records and mirror data\n through mapped I/O units, keeping neighboring records intact when\n multiple records share a native 4Kn block. Track folio writeback\n until all BIOs complete, serialize raw record updates against\n writeback, and use the caller\u0027s requested completion mode.\n\n - Discard stale uninitialized cache data before extending initialized\n size, ensure shared mmap writes update initialized size after\n native 4Kn size extension, and synchronize attribute inode sizes\n after internal resizes. Keep VFS and NTFS sizes consistent when\n write-error rollback fails and record the volume error.\n\n - Wait for existing folio writeback before updating attribute data,\n require page alignment for full-page write optimizations, and\n include the final partial cluster in synchronous writes. Skip\n duplicate VFS page-cache truncation under the MFT record lock to\n avoid a truncate and writeback deadlock.\n\n - Restart allocation zone searches after failed hints and prevent\n contiguous allocation requests from returning additional disjoint\n runs that callers leave uninitialized. Allow fallocate after\n MFT-zone exhaustion and interrupt allocation loops only for fatal\n signals, avoiding spurious interruptions from io_uring task-work\n notifications.\n\n - Wait for the initial bitmap scan before extending the MFT bitmap,\n bound direct allocation candidates by the volume size, update\n free-space accounting, and undo only newly allocated clusters after\n run coalescing. Update attribute-list inode size before reserving\n additional space.\n\n - Hold runlist locks while expanding non-resident attributes, balance\n locks during MFT extension error handling, and avoid pointers\n invalidated by runlist reallocation. Keep source runlists available\n for rollback and allocate enough room for runlist markers and\n terminators.\n\n - Return errors for unmappable runlist fragments instead of treating\n them as holes or delayed allocation. Check non-resident attribute\n sizes against their allocation and fail mounts when $MFT needs\n extent records outside the decoded runlist to describe itself,\n preventing silent zero reads and mount hangs.\n\n - Load and validate $BadClus:$Bad at mount time and reserve known bad\n clusters before the free-space scan. Fall back to read-only\n operation when bad-cluster metadata cannot be validated and prevent\n subsequent read-write remounts.\n\n - Serialize volume flag updates and retain the dirty bit after\n metadata changes while the volume remains mounted read-write.\n Persist recorded errors after final metadata commits, fail ordinary\n read-only remounts on sync, commit, or flush errors, and retain the\n dirty bit on forced remounts.\n\n - Flush the device write cache when syncing directories and report\n flush failures from both file and directory fsync. Drain in-flight\n direct I/O before buffered write fallback and keep nonblocking\n requests from entering the blocking fallback path.\n\n - Mount hibernated volumes, or volumes whose hibernation state cannot\n be determined, read-only regardless of the errors\u003d policy. Prevent\n mount-time and dirty-state updates from modifying hibernated\n volumes.\n\n - Validate complete EA chains, link zero-terminated tails when\n appending entries, retain the EA presence flag, and distinguish\n empty values from removal. Propagate lookup, write, and truncate\n errors, restore both EA attributes after failed updates, and shut\n down the volume if restoration fails.\n\n - Restore the previous ACL xattr when a subsequent WSL mode update\n fails, including replacement and removal cases. Record rollback\n failures so an unsuccessful permission change cannot silently leave\n inconsistent ACL and mode state.\n\n - Apply MST fixups to individual index blocks on large-page systems\n and use fixed 512-byte VCN units when an index block is smaller\n than its cluster. Support lookup and removal of POSIX names\n containing Windows-invalid characters and identify directory\n symlinks and junctions during enumeration.\n\n - Report the stored creation time for symbolic links through statx()\n when querying the link itself with AT_SYMLINK_NOFOLLOW.\n\n - Use wider decompression offsets to avoid overflow on 64 KB pages,\n accept the standard sparse compression unit, and require the\n compressed-size field only on the first attribute extent. Block\n direct reads and skip readahead for encrypted files to prevent\n returning raw ciphertext.\n\n - Validate index entry offsets, logfile update sequence array counts,\n attribute-list sizes, and index collation key lengths to prevent\n out-of-bounds accesses, NULL pointer dereferences, and excessive\n allocations from corrupt volume metadata.\n\n - Derive FITRIM bitmap indexes from the page size and retain the full\n 64-bit minimum discard length. Balance highmem mappings in logfile\n and MFT mirror checks and propagate specific errors from extent,\n attribute, and reparse operations.\n\n - Compare streams_interface with the mounted volume\u0027s setting during\n remount, make named-stream UAPI padding explicit, document stream\n access and Linux file attributes, and add the NTFS UAPI header to\n MAINTAINERS\"\n\n* tag \u0027ntfs-for-7.4-rc1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfs: (93 commits)\n ntfs: handle a failed size rollback in the write error path\n ntfs: fix u16 truncation of the update sequence array count check\n ntfs: reject index blocks with a too small entries offset\n ntfs: support persistent noatime attribute\n ntfs: roll back the ACL xattr commit when the WSL mode update fails\n ntfs: report birth time for symbolic links\n ntfs: support FS_IOC_GETFSUUID\n ntfs: avoid unnecessary padding in uapi structure\n ntfs: flush the block device when syncing a directory\n ntfs: report block device flush failures from fsync\n ntfs: fix NULL dereference on index allocation open failure\n ntfs: compare streams_interface with mounted volume on remount\n ntfs: widen the sub-block offsets in ntfs_decompress()\n ntfs: reject direct I/O reads of encrypted files\n ntfs: do not read ahead encrypted files\n ntfs: persist nodump in the $LINUXFLAGS EA\n ntfs: persist append-only in the $LINUXFLAGS EA\n ntfs: persist immutable in the $LINUXFLAGS EA\n ntfs: add fileattr query support\n ntfs: restore EA attributes when an update fails\n ...\n" }, { "commit": "42023dd0a294d8b5c05127dcf95987b70c2fb271", "tree": "67e02680453b4e16ffd7bf9bbf9cbc28290c4353", "parents": [ "4e1b4fdf6113b4eb9564bdf3b76ee3c3132da7d4", "8534eb11ac056dc2ca08007cf76d3ae7cbe42684" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Oct 25 15:54:05 2026 -1000" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Oct 25 15:54:05 2026 -1000" }, "message": "Merge tag \u0027exfat-for-7.4-rc1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/exfat\n\nPull exfat updates from Namjae Jeon:\n\n - Use the recalculated append position when advancing valid_size, dirty\n all pages involved in valid-data extension, and zero invalid tails on\n partial overwrites.

This prevents an unresponsive rpcbind from stalling NFSD\n administration for a minute at a time.\n\n Bulk delegation recall now adjusts the number of delegations it\n wants returned, based on memory pressure. The previous mechanism\n was spec-conformant, but it requested all delegations to be\n returned at once. Clients are free to return few or none in such\n cases, but requesting smaller batches of delegations is more\n neighborly.\n\n In preparation for handling TLS KeyUpdate, the server\u0027s TCP\n receive path has been reworked to handle control records. In the\n process, the use of sock_recvmsg was replaced with -\u003eread_sock,\n which contends less with other holders of the socket lock.\n\n NFSv2 XDR code is now generated by xdrgen, which mechanically\n generates the encoders and decoders from the RPC language\n specification for the protocol. Replacing hand-built XDR code\n makes prototyping new protocol elements faster, reduces errors,\n and improves memory safety. Replacement of XDR code for newer NFS\n versions will continue in subsequent releases of NFSD.\n\n The remaining bulk of changes in v7.4 is bug fixes, clean-ups, and\n small optimizations.

Guarantee asynchronous packet and transaction callbacks in process\n context\n\n Both the 1394 OHCI driver and the core transaction layer have been\n changed to guarantee that asynchronous packet and transaction\n callbacks are invoked in process context. In v6.17, the execution\n context depended on the transaction destination: callbacks for\n transactions destined for remote nodes were invoked from a workqueue,\n whereas callbacks for transactions destined for the local node or\n terminated due to internal errors were invoked in the transaction\n initiator\u0027s context.\n\n All such callbacks are now guaranteed to execute in process context,\n eliminating the need to account for different execution contexts when\n implementing callback functions.\n\n - Fill kerneldoc for transaction layer\n\n The above change guarantees a consistent execution context for packet\n and transaction callbacks, making it possible to document their\n execution context in kerneldoc.\n\n - Enable compiler-based context analysis for the transaction layer\n\n The core transaction layer is sufficiently complex that\n compiler-based context analysis can help detect invalid call paths.\n\n - Fix a reference count leak in the cdev layer\n\n A reference count leak was reported when a user space application\n delegated isochronous resource management. This issue has now been\n fixed.\n\n - Add KUnit tests for the configuration ROM parser and generator\n\n In recent years, questions have been raised about how the\n configuration ROM parser and generator handle boundary conditions and\n edge cases. KUnit tests have been added to verify their behavior in\n these situations. KUNIT_STATIC_STUB_REDIRECT is used to stub the\n transaction responder so that it returns the configuration ROM\n contents.\n\n - Misc fixes for kerneldoc and nosy-dump application\n\n* tag \u0027firewire-updates-7.4\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394: (88 commits)\n firewire: core: replace drain_workqueue() with flush_workqueue()\n firewire: core: adjust context_unsafe() usage for lockdep checks\n firewire: core: invoke packet callback from workqueue when removing card instance\n firewire: core: use designated initializer for dummy driver on card removal\n firewire: core: use context analysis to check lock state when scheduling error callbacks\n firewire: core: check precondition when scheduling error callbacks\n firewire: core: use workqueue to cancel all pending transactions on card removal\n firewire: core: reuse helper function for scheduling error callbacks\n firewire: core: don\u0027t disable error work for transaction\n firewire: core: use release/acquire pair when replacing underlying driver on card removal\n firewire: core: add kerneldoc for inbound transaction-related symbols\n firewire: core: add kerneldoc for outbound transaction-related symbols\n firewire: core: use appropriate spinlock variants for transaction-related locks\n firewire: core: narrow the card lock scope when accessing node_id\n firewire: core: use context analysis annotations and lockdep checks for topology map lock\n firewire: core: use context analysis annotations and lockdep checks for split timeout lock\n firewire: core: use context analysis annotations and lockdep checks for transactions lock\n firewire: core: enable context analysis for transaction layer\n firewire: core: add might_sleep() checks to transaction layer\n firewire: core: fulfill kerneldoc for fw_cancel_transaction()\n ...\n" }, { "commit": "42e6549eafc66f3648319585680ba0c71c2461da", "tree": "193b190eeffd9a74add00d8f0ff9e06f32fef8b3", "parents": [ "75c1cb8178fe84403fd95236ddf21754f0a4156c", "d7e7bca7169873b46e857c025c10f3336c1258d8" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Oct 24 19:27:32 2026 -1000" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Oct 24 19:27:32 2026 -1000" }, "message": "Merge tag \u0027media/v7.4-1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media\n\nPull media updates from Mauro Carvalho Chehab:\n\n -

Set supported_speeds in set_pcie_port_type() so sparc64 and\n powerpc, which call it via of_create_pci_dev() instead of the usual\n pci_setup_device(), correctly set the supported PCIe link speeds\n (Stian Halseth)\n\n - When pcie_set_mps() changes MPS, update the value in the saved\n state so a subsequent restore doesn\u0027t restore an invalid value\n (Niklas Cassel)\n\n - Skip Target Speed quirk on clamped ports with no link (Maciej W.\n Rozycki)\n\n Driver binding:\n\n - Assume control of portdrv-related features only when portdrv is\n enabled, since we can\u0027t use them without portdrv (Kuppuswamy\n Sathyanarayanan)\n\n - Centralize feature ownership checking so code only needs to check\n \u0027host-\u003enative_X\u0027 and doesn\u0027t need to also check \u0027pcie_ports_native\u0027\n (Kuppuswamy Sathyanarayanan)\n\n Error handling:\n\n - Fix leaks when ACPI APEI/GHES error events overflow the kfifo or\n mention a device that no longer exists (Priyank Rathod)\n\n - Fix aer_process_err_devices() leak when a device is recorded as an\n error source purely by being mentioned in the Root Port Error\n Source and the device is inaccessible or logged only masked errors\n (Priyank Rathod)\n\n ASPM:\n\n - Disable ASPM when drivers request that, even if the OS doesn\u0027t own\n ASPM; otherwise drivers do it on their own, which is worse (Ilpo\n Järvinen)\n\n Power management:\n\n - Align hibernate poweroff flow with suspend flow for bridges so they\n can be powered down at hibernate as they are for suspend (Mario\n Limonciello)\n\n - Restore BARs after powering up during enumeration to fix a\n regression on devices that don\u0027t preserve state in D3hot (Keng-Yu\n Lin)\n\n - Avoid D3 on PLX PEX 8532/8533/8548 downstream ports, where putting\n them in D3hot takes down the whole switch (Imre Kaloz)\n\n Power control:\n\n - Add GPIO driver for Toshiba TC9563 embedded GPIO controller (Alex\n Elder)\n\n - Add DT documentation and pwrctrl driver support for TC9563 embedded\n GPIO controller (Lorenzo Bianconi)\n\n - Switch the tc9563 per-port reset to use the GPIO descriptor API\n instead of direct regmap accesses (Lorenzo Bianconi)\n\n - Only destroy devices created by pwrctrl core, so that when removing\n a PCIe controller driver that uses pwrctrl, we don\u0027t remove devices\n populated by another mechanism (Shawn Lin)\n\n - Power off child devices on power-on failure (Lorenzo Bianconi)\n\n PCIe native device hotplug:\n\n - Make the \u0027pciehp_poll_mode\u0027 parameter read-only to prevent changes\n via sysfs, which can cause errors when unbinding (Runyu Xiao)\n\n Virtualization:\n\n - Read SR-IOV VF Revision ID and Subsystem ID from VF instead of\n assuming they\u0027re the same as VF 0; they may differ (Logan Odell)\n\n - Add ACS quirk for Pericom PI7C9X2G304 switches (Hans de Goede)\n\n Peer-to-peer DMA:\n\n - Add Zhaoxin KX-6000, KH-40000, KX-6000G, KX-7000, and KH-50000 host\n bridges to allowlist (LeoLiu-oc)\n\n - Add Alibaba T-HEAD Yitian 710 host bridge to allowlist (Feng Tang)\n\n - Add Intel Haswell client host bridge to allowlist (Scott Lee)\n\n - Intel Xeon E3/E5/E7 0x6f00 host bridge to allowlist (kai zhang)\n\n - Fix handling of errors in pci_p2pdma_add_resource() to avoid (a)\n unmapping a BAR if registering another fails and (b) use after free\n of p2p_pgmap (Leon Romanovsky)\n\n - Wait for RCU readers before freeing state to avoid use-after-free\n of pdev-\u003ep2pdma (Leon Romanovsky)\n\n - Restrict pci_p2pmem_find_many() to providers backed by a pool (Leon\n Romanovsky)\n\n - Safely terminate ACS redirect lists to avoid out-of-bounds access\n to the buffer (Leon Romanovsky)\n\n - Silence \u0027Host bridge not in P2PDMA whitelist\u0027 warnings unless\n caller, e.g., pci_p2pmem_find_many(), requests \u0027verbose\u0027 (Leon\n Romanovsky)\n\n Sysfs:\n\n - Return -ENODEV or -EIO sysfs \u0027label\u0027 or \u0027acpi_index\u0027 attributes\n when Device Name _DSM fails, not -1, which is interpreted as -EPERM\n (Krzysztof Wilczyński)\n\n - Return valid sysfs \u0027acpi_index\u0027 attribute even if the Device Name\n _DSM returned an invalid \u0027label\u0027 (Krzysztof Wilczyński)\n\n - Expose sysfs \u0027acpi_index\u0027 and \u0027label\u0027 based on whether the Device\n Name _DSM returns valid data, not merely whether the _DSM is\n implemented (Krzysztof Wilczyński)\n\n - Avoid out-of-bounds reads of the label returned by the Device Name\n _DSM, which is in UTF-16 characters, not bytes (Krzysztof\n Wilczyński)\n\n - Reject unaligned resource I/O port accesses, which can oops on\n arm64 (Deepanshu Kartikey)\n\nEndpoint framework:\n\n - Pass the correct physical and virtual endpoint function numbers\n when setting translation of inbound memory windows (Koichiro Den)\n\n - Make embedded doorbell IRQ non-shared, since currently only the\n first EPF can allocate doorbells (Koichiro Den)\n\n - MSI doorbells currently target the first EPF attached to an EPC;\n let other EPFs try the embedded doorbell instead of failing when\n they can\u0027t use the MSI doorbell (Koichiro Den)\n\n -

This prevents KVM from sampling\n untrusted values\n\n - Restore some type checking to the EL2 object. KVM/arm64 originally\n had some strong type checking between the kernel and the EL2\n object, but lost it along the way when the private hypercall\n interface was (somewhat pointlessly) converted to SMCCC. Type\n checking is back, syscall style, and with added sparse goodies\n\n - Expand the FFA support to FFA_NOTIFICATION_*, and add some\n sanitisation of the protocol that pKVM relays to the \"trusted\"\n runtime\n\n - Make GICv3 RD assignment more robust to userspace nonsense\n\n - Convert the remaining MMU fault handler backends to\n kvm_s2_fault_vma_info and co., fixing a number of bugs in the\n process\n\n - Fix the SError/SEA selftests to be both more robust and less\n braindead\n\n - Fix a smattering of documentation bugs, some of them as a result of\n our AI friends spitting out credible assertions based on\n non-existing symbols\n\n - The usual collection of low impact bug fixes (SMCCC, timers, PMU)\n\n Loongarch:\n\n - Add separate vmid support\n\n - Simplify MSI interrupt injection\n\n - Add crash hypercall support\n\n - Allow to set pv_feature until vCPU run\n\n - Enable HW page table walk automatically in selftests\n\n s390:\n\n - rework page allocation for secure guest variable storage\n\n - Selftests and documentation improvements\n\n - Replace get_zeroed_page with kzalloc\n\n - Fix corner cases of floating interrupt injection\n\n - Initial arm64 on s390 support\n\n x86:\n\n - Clean up the handling of vcpu-\u003earch.xen.long_mode to be consistent\n and correctly handle 32-bit/64-bit alignment, and various other bug\n fixes have accumulated over the months since v1\n\n - Grab KVM\u0027s SRCU \"lock\" in kvm_zap_gfn_range() to fix a recurring\n bug where callers fail to do so\n\n - Fix a variety of issues in the pre-fault code that are mostly\n benign in the current code base, but will show up in big ways\n if/when the pre-faulting logic is used to implementing\n prefetch-on-fault for the TDP MMU\n\n - For PREEMPT_RT\u003dy kernels, drop the rmaps\u0027 individual bit-spinlock\n and just walk the rmaps\u0027 with mmu_lock taken. On the write side\n (which always uses mmu_lock), the bit-spinlock was assuming that\n preemption was disabled, but that is *not* true when rwlocks become\n sleepable\n\n - Prepare a memory_fault exit (paired with -EFAULT) when KVM hits an\n error PFN, e.g. so that userspace can resolve transient issues\n instead of killing the guest. Convert a variety of WARN()+EFAULT\n paths into KVM_BUG_ON()+EIO so that KVM can hard commit to filling\n memory_fault on -EFAULTs that occur in the page fault path\n\n - Fix a NX hugepage un-accounting bug where KVM would always uncharge\n the shadow MMU, even when handling TDP MMU pages\n\n - Mask off the address space ID when checking for illegal usage of\n kvm_set_internal_memslot() to prevent false negatives on the sanity\n check\n\n - Explicitly zero reserved flags when delivering a SynIC message to\n avoid leaking a byte of stack information to the guest\n\n - Rework TDX\u0027s handling of the canonical MMU root level to not rely\n on userspace to fill CPUID correctly, as doing so lets userspace\n trivially trigger a KVM_BUG_ON()\n\n - Reject KVM_SET_NESTED_STATE if userspace \"restores\" L1 with\n EFER.LMA\u003d1 \u0026\u0026 EFER.LME\u003d0, which confuses KVM into trying to\n configure an 64-bit MMU without PAE\n\n - Ignore EFER.LMA (clear it from KVM\u0027s cached save state) if\n EFER.LME\u003d0 when preparing L2 state, to fix another way to confuse\n KVM\u0027s MMU (and because real hardware also ignores EFER.LMA)\n\n - Improve KVM\u0027s sanity checks for a misconfigured MMU to (hopefully)\n detect all of the ways KVM can botch EFER.LMA vs. CR4.PAE\n\n - Remove the \"full\" out-param from kvm_x86_ops.flush_tlb_gva() as the\n param is only used to avoid what effectively amounts to a single\n memory write\n\n - Fix a mostly-benign bug where KVM can write through a guest\u0027s\n read-only mapping due to not checking the error code when\n expediting emulated MMIO page faults\n\n - Honor the guest\u0027s view of the \"EFER.LMSLE must be zero\" defeature\n so that userspace can provide migration compatibility between Rome\n and Milan+\n\n - Pend a KVM_REQ_EVENT request when an exception is morphed into a\n nested VM-Exit, otherwise KVM can fail to actually deliver the\n nested VM-Exit, e.g. when injecting a page fault\n\n - Add support for PML on SVM\n\n - Add support for virtualizing Bus Lock Detect on SVM, and fix a\n number of DR6 bugs and warts along the way\n\n - Fix a variety of warts in KVM\u0027s handling of guest TSC, kvmclock,\n and timekeeping in general, as a (big) first step towards\n addressing several longstanding problems with the kvmclock\n implementation. Most notably, fix a precision issue where\n get_kvmclock_ns() computed the clock from the *host* TSC without\n applying guest TSC scaling, causing systemic drift from the values\n the guest computes from its own TSC\n\n - Rip out KVM\u0027s shadow timekeeping structures, now that ktime\n snapshots are powerful enough to replace it\n\n - Misc fixes and cleanups\n\n x86 (AMD):\n\n - Fix a benign-in-practice bug where KVM unintentionally sets a\n non-zero error code when delivering exceptions to SEV-ES+ guests\n\n - Force a new ASID in both VMCBs on pCPU migration to fix a bug where\n KVM can run a VMCB with a stale ASID due to the tracking being\n per-CPU, not per-VMCB\n\n - Return INVALID_INPUT to the guest instead of exiting to userspace\n with -EIO if KVM can\u0027t access \"guest request\" buffer, i.e. try to\n keep the guest alive if the guest or userspace goofs\n\n x86 (Intel):\n\n - Enable Notify VM-Exits (now called Instruction Timeout in the SDM)\n and Bus Lock VM-Exits for TDX guests when they\u0027re enabled by\n userspace (KVM forgot to wire up the TDX Module knobs)\n\n - Move all common (between VMX and TDX) APIs/helpers to\n common.h/main.c, and change all namespace prefixes from \"vmx\" to\n \"vt\"\n\n - Fix a thankfully benign bug (due to other areas of KVM being\n hardened) where userspace can bypass INIT_MEM_REGION\u0027s address wrap\n check by providing a nr_pages that will overflow a u64 when\n converted to bytes, and fix an also- benign off-by-one bug in the\n check (inclusive vs. exclusive)\n\n - Set the vmcs.GUEST_ACTIVITY_STATE back to ACTIVE when userspace\n sets KVM\u0027s mp_state to anything other than HALTED, e.g. so that a\n vCPU doesn\u0027t get stuck in HLT if userspace emulates RESET\n\n guest_memfd:\n\n - Take the invalidate lock when unbinding a dying file to fix a race\n with kvm_gmem_invalidate_end() that results in KVM leaving the MMU\n invalidation count elevated. Not taking the lock in the first place\n was pure misguided paranoid\n\n - When binding a memslot, purge the bindings if storing the new\n memslot fails, as Xarray\u0027s \"store range\" API can subtly fail\n partway through\n\n - Establish memslot\u003c\u003d\u003eguest_memfd bindings *after* the memslot is\n ready, as the memslot becomes reachable the instant the binding is\n installed\n\n - Don\u0027t grab a page refcount when reloading an SNP VMSA and stop\n returning a \"struct page\" from guest_memfd\u0027s PFN lookup altogether,\n to ensure that KVM doesn\u0027t hold any unnecessary refcounts (the\n lifetime of the page is ensured by MMU notifiers and similar\n hooks). Preventing unnecessary refcounts greatly simplifies\n supporting in-place SHARED\u003d\u003ePRIVATE conversions\n\n - Add support for in-place PRIVATE\u003c\u003d\u003eSHARED conversion, i.e. allow a\n single guest_memfd instance to be used for both PRIVATE and SHARED\n variations of CoCo guests\u0027 memory (though not at the same time).\n This eliminates the need to double allocate guest memory for TDX\n and SNP, and is basically a hard requirement for pKVM, which relies\n on being able to preserve memory contents on conversions\n\n - Hack-a-fix a deadlock bug in -\u003eerror_remove_folio() by returning\n -EBUSY if the filemap invalidate lock is contended. Punt on a\n proper fix for the moment, as a proper fix likely involves\n reworking truncate_error_folio()\n\n - Add a pile of selftests for in-place conversions\n\n - Misc guest_memfd cleanups\n\n Generic:\n\n - Move some configuration items to preprocessor symbols, to help with\n arm-on-s390\u0027s need to compile the same code twice with different\n values\n\n - Allow KVM implementations to choose alternative device names, also\n for s390\u0027s support of ARM virtualmachines\n\n - Switch the KVM-VFIO interface and external consumers over to\n standard file-based reference counting, eliminating all external\n KVM symbol exports\n\n Selftests:\n\n - Rework KVM selftest\u0027s handling of memory regions all so that PPC\n can force its page table allocations to be naturally aligned\n\n - PPC support\n\n - Fix emulation of VMPTRST and VMPTRLD when eVMCS is in-use to match\n real Hyper-V\u0027s behavior\n\n - Saturate L2\u0027s TSC frequency if stacking L1 and L2 scaling\n multipliers exceeds what hardware supports, as attempting to run L2\n with an illegal multiplier will either cause VM-Entry to fail (VMX)\n or trigger a #GP when writing MSR_AMD64_TSC_RATIO (SVM). The #GP is\n thankfully benign in the grand scheme as even \"unsafe\" WRMSRs have\n exception fixup\n\n - Rework KVM selftest\u0027s handling of memory regions so that PPC can\n force its page table allocations to be naturally aligned\n\n - Clean up selftest\u0027s VMX instruction helpers, and drop an absurd\n number of completely useless return values, e.g. functions that\n unconditionally return %true and then have every caller assert\n success\n\n - Add selftests support for Zhaoxin CPUs\n\n - Overhaul the TSC scaling test to add a regression test for the\n saturation behavior, and to increase its coverage in general\n\n - Fix selftests usage various NUMA syscalls to account for an\n undocumented, but known since 2007, off-by-one kernel bug. Add\n helpers to try and avoid re-introducing the same flaws in the\n future\n\n - Automatically run xAPIC IPI migration test (between NUMA nodes)\n when possible, as the entire point of the test is verify KVM\u0027s\n handling of page migration of the APIC backing page\n\n - Misc cleanups\"\n\n* tag \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/virt/kvm/kvm: (506 commits)\n KVM: always make in-place conversion a compile-time constant when possible\n KVM: x86: leave the legacy private attribute in for TDX and SEV\n KVM: split CONFIG_KVM_PRIVATE_MEMATTR_VM out of KVM_VM_MEMORY_ATTRIBUTES\n selftests: kvm: remove useless comma operator\n arm64: Use proper include variant\n MAINTAINERS: Add entry for ARM on s390 KVM\n KVM: s390: arm64: Integrate arm on s390\n KVM: s390: arm64: Implement basic page fault handler\n KVM: s390: arm64: Implement vCPU IOCTLs\n KVM: s390: arm64: Implement vm/vcpu create destroy\n KVM: s390: arm64: Implement required functions\n KVM: s390: Add basic arm64 kvm module\n s390/hwcaps: Report SAE support as hwcap\n KVM: s390: arm64: Introduce host definitions\n s390: Introduce Start Arm Execution instruction\n KVM: s390: Use arm64 code\n s390/tools: Use arm64 headers\n KVM: s390: Use dedicated function for migration mode\n s390/Kconfig: remove PCI dependency from HAS_IOMEM\n KVM: s390: Kick PV cpus at the right time for service irqs\n ...\n" }, { "commit": "55fbedcec622a943cb09a969aef1ddcba87ee40a", "tree": "99bf57398ef32396f831f31efffb5d917ce22e0c", "parents": [ "90b754d40117b2889bbe847ce7bb4dcf968e7cb8", "b116ac6087541d3d98031e786adbe9c733cd6df3" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Oct 23 13:08:49 2026 -1000" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Oct 23 13:08:49 2026 -1000" }, "message": "Merge tag \u0027bpf-next-7.4\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next\n\nPull bpf updates from Alexei Starovoitov:\n \"Major changes:\n\n - Introduce scalar evolution (SCEV) analysis in the verifier.\n\n It infers how registers and stack slots change in a loop and lets\n the verifier check bounded loops with induction variables as ranges\n instead of walking every iteration.

Race collapse against faults, pinning, fork\n and remap; verify that the contents survive.\n\n Add coverage for whole-page-table zaps and memory pressure too.\n\n - \"selftests/mm: separate GUP microbenchmarking from functional testing\"\n (Sarthak Sharma):\n\n Untangle GUP benchmarking from correctness testing. Move the\n benchmark into tools/mm, add a standalone harness-based GUP selftest,\n and move shared helpers into tools/lib/mm. Give each tool one job\n instead of mixing timing measurements with correctness checks.\n\n Cover the mapping, pinning and batch-size combinations explicitly.\n\n - \"mm: Switch device DAX to section-based vmemmap optimization\" (Muchun\n Song):\n\n Apply section-based vmemmap optimization to device DAX. Rework the\n backing metadata layout to save memory while preserving the handling\n of device memory hotplug and its different alignment and lifetime\n requirements.\n\n - \"mm: Introduce section-based vmemmap optimization for HugeTLB\"\n (Muchun Song):\n\n Cut the memory consumed by HugeTLB\u0027s struct page array with\n section-based vmemmap optimization. Arrange the metadata so large\n huge pages need fewer backing pages, while keeping initialization,\n teardown and the various hugepage configurations straight.\n\n - \"mm/huge_memory: clean up and decouple the anon and file split\n helpers\" (Kairui Song):\n\n Separate anonymous and file-backed folio splitting, which have rather\n different locking and bookkeeping requirements. Move the work into\n separate helpers, drop dead checks and tidy swap-cache handling. Fix\n error paths, including one that could leave a folio frozen.\n\n Keep the swap cache cases separate from file-cache splitting.\n\n - \"mm: Unconditional per-VMA locks and cleanups\" (Dave Hansen):\n\n Make per-VMA locking unconditional and clean up the old conditional\n code around it. This removes configuration-dependent plumbing and\n lets callers depend on one locking model rather than carrying both\n cases along.\n\n - \"memcg: remove the v1 soft limit\" (Shakeel Butt):\n\n Remove the old cgroup v1 memory soft-limit machinery. This has long\n since been superseded by the newer memory-control interfaces; hauling\n around a separate reclaim scheme for it no longer buys us much.\n\n - \"read proc/pid/smaps_rollup under per-vma lock\" (Suren Baghdasaryan):\n\n Read /proc/PID/smaps_rollup using per-VMA locks where possible,\n rather than holding mmap_lock across the entire walk. Retain the\n contention fallback and add tearing tests. This considerably reduces\n latency when another thread is busy changing its mappings.\n\n - \"mm/damon: introduce data access-as-a-data attribute\" (SJ Park):\n\n Teach DAMON to expose memory access observations as data attributes,\n making them available to the probe and filtering machinery. Extend\n the interfaces, documentation and tests so the new information can be\n used rather than merely collected.\n\n - \"Remove PG_private by using page/folio-\u003eprivate checks instead\" (Zi\n Yan):\n\n Get rid of PG_private and use the folio\u0027s private pointer to say\n whether private data is attached. Convert the filesystem users,\n including erofs, f2fs and md, and clean up the old accessors and\n flags. There are a few special cases, notably swapcache and hugetlb,\n which need explicit care.\n\n - \"mm: make userland page table freeing RCU-safe\" (Lorenzo Stoakes):\n\n Make freeing userspace page tables safe against RCU readers. Sort out\n the page-table lifetime and locking rules so walkers cannot stumble\n over freed tables while mappings are being torn down.\n\n - \"make unused huge shrinker memcg aware\" (Qi Zheng):\n\n Make shmem\u0027s unused-huge-folio shrinker aware of memory cgroups, so\n reclaim can find those folios under the right memcg. Wire up the\n per-memcg tracking and its lifetime rules, and give the shrinklist\n its own lockdep class to avoid spurious dependency reports.\n\n - \"mm: Drop pxd_ERROR()\" (Anshuman Khandual):\n\n Remove the old pxd_ERROR() page-table checks and their\n architecture-specific baggage. Simplify the common page-table\n interfaces and callers now that these checks no longer serve a\n useful purpose.\n\n - \"memcg: group struct fields by access pattern\" (Shakeel Butt):\n\n Rearrange memcg\u0027s hot and cold fields according to how they\u0027re\n actually accessed. Keep frequently updated counters and their\n neighboring state from fighting over cachelines and reduce needless\n cacheline traffic.\n\n - \"mm/damon/core: fix the size charged for a filter-trimmed region\"\n (Donggeun Yoo):\n\n Fix DAMOS quota accounting when a filter trims a monitoring region.\n Charge only the part left after filtering, not the original region,\n and add KUnit coverage. Previously the excluded memory could eat into\n the quota and make schemes run more slowly than requested.\n\n - \"mm/damon: add kunit and selftests for probes and probe weights\" (SJ\n Park):\n\n Add more tests for DAMON probes and their weights, including\n validation and the results reported to userspace. This is mostly\n about catching regressions in the newer probe infrastructure before\n they become harder to diagnose.\n\n - \"mm: memcontrol: constify the read side of the read side of the memcg\n API\" (Tal Zussman):\n\n Mark the read-only parts of the memcg interface const, from folio and\n lruvec accessors to counters and swap helpers. Most of this is\n mechanical, but it makes the contracts clearer and lets the compiler\n catch accidental writes.\n\n - \"mm/damon/vaddr: support {prep,apply}_probes\" (SJ Park):\n\n Support the new prepare/apply probe operations in DAMON\u0027s\n virtual-address backend. This brings vaddr monitoring into line with\n the probe infrastructure and makes the added probe types useful there\n too.\n\n - \"mm/mglru: clean up folio counters and flag usage\" (Kairui Song):\n\n Simplify MGLRU\u0027s folio counters and flag handling. Remove redundant\n accounting paths and make the state transitions easier to follow\n without changing the intended reclaim policy.\n\n - \"arch, mm/execmem: resolve confusion about set_direct_map_valid_noflush()\"\n (Mike Rapoport (Microsoft)):\n\n Clarify and straighten out the set_direct_map_valid_noflush()\n interface across architectures and execmem. Make the requested\n mapping changes and the callers\u0027 expectations agree, rather than\n relying on subtly different architecture behavior.\n\n - \"mm: zswap: free cold writeback folios promptly\" (Alexandre Ghiti):\n\n Free zswap writeback folios as soon as their disk write completes.\n They are cold temporary buffers, so putting them on the LRU only\n makes reclaim rediscover them later. Extend swap-cache dropbehind and\n let zswap keep these folios off the LRU altogether.\n\n - \"mm: gup: cleanup gup_fast call chain\" (Aristeu Rozanski):\n\n Clean up the GUP-fast call chain and simplify how the fast-path\n helpers pass their arguments and results around. Keep the page-pin\n behavior the same while making the call sequence easier to maintain.\n\n - \"mm: optimize zone-device memmap initialization\" (Li Zhe):\n\n Speed up initialization of zone-device struct pages. Avoid redundant\n work when setting up large device-memory ranges, where touching every\n descriptor can get expensive.\n\n - \"mm/zswap: shrink zswap_entry via a pool id\" (Jianyue Wu):\n\n Reduce the size of zswap_entry by storing a compact pool identifier\n instead of a full pointer. Keep the pool lookup and lifetime handling\n correct while saving per-entry metadata.\n\n - \"mm/damon: support access monitoring of hugetlb-backed memory\"\n (Krishna Iyer):\n\n Let DAMON monitor hugetlb-backed memory too. Extend the relevant\n access checks and add coverage so those mappings no longer fall\n through a hole in the monitoring machinery.\n\n - \"mm/execmem: fixes and cleanups for the ROX cache\" (Mike Rapoport):\n\n Tidy execmem\u0027s read-only-executable cache and fix its handling of the\n awkward allocation and release cases. The aim is to make the cache\u0027s\n ownership and permission transitions more predictable.\n\n - \"zsmallc: remove old object read API\" (Sergey Senozhatsky):\n\n Drop zsmalloc\u0027s old object-read API and move its remaining users to\n the supported access mechanism. This removes a duplicate interface\n which we no longer need.\n\n - \"mm/mempolicy: stop copying state in the interleave paths\" (Gregory\n Price):\n\n Stop copying mempolicy state in the interleave paths when a reference\n to the existing policy will do. This avoids extra work and makes the\n ownership rules less obscure.\n\n - \"mm/mglru: speed up inc_min_seq() and fix cold/hot inversions\" (Barry\n Song):\n\n Make MGLRU\u0027s generation advancement cheaper and fix cases where cold\n and hot folios end up in the wrong order. Adjust the counter and list\n handling so reclaim doesn\u0027t keep passing over the better eviction\n candidates.\n\n - \"mm: Fix MF_DELAYED handling on memory failure\" (Lisa Wang):\n\n Treat MF_DELAYED as a partially completed memory-failure operation,\n not an outright failure. Propagate that result correctly through\n shmem and the generic handler, fix the extra-reference accounting,\n and add tests for the resulting SIGBUS behavior.\n\n - \"tools/mm/page_owner_sort: fix --sort, add module filter, improve\n usage\" (Ye Liu):\n\n Fix page_owner_sort\u0027s --sort handling, add module-based filtering and\n make the usage output more helpful. This makes the tool less\n frustrating when tracking down who is holding on to pages.\n\n - \"mm/damon: move damos filter range arguments validation to core\" (SJ\n Park):\n\n Move DAMOS filter range validation into the core, where all callers\n can share it. Also close the sysfs read-twice races which could pass\n inconsistent ranges, and add tests for invalid input.\n\n - \"mm/damon: misc cleanups\" (Zenghui Yu):\n\n Clean up a collection of small DAMON rough edges in the core,\n interfaces and tests. No large behavior change here, just simpler\n code and fewer opportunities for confusion.\n\n - \"mm/damon: cleanup code, add test cases, and update guidances in\n docs\" (SJ Park):\n\n Clean up DAMON\u0027s core and interfaces, add missing test cases and\n bring the documentation into line with the code. These changes should\n make the newer facilities easier to understand and maintain.\n\n - \"mm/damon: introduce hugepage_size probe filter\" (SJ Park):\n\n Add a DAMON probe filter for hugepage size. Let users select a range\n of folio sizes through sysfs, validate the range and document the new\n interface, so monitoring can concentrate on memory backed by the\n desired hugepage sizes.\n\n - \"selftests/mm: pagemap_ioctl test fixes and cleanups\" (Zenghui Yu):\n\n Fix some pagemap ioctl test assumptions and clean up their setup and\n reporting. Make failures point to the operation that went wrong\n rather than to test harness bookkeeping.\n\n - \"mm: avoid large folio splits when swap is unavailable\" (Johannes\n Weiner):\n\n Avoid splitting large folios merely to attempt swap when no swap\n space is available. There is little point paying for an expensive\n split when reclaim cannot actually swap the resulting pages out.\n\n - \"mm: workingset: fix the shadow node budget under MGLRU\" (Hui Zhu):\n\n Fix the workingset shadow-node budget with MGLRU enabled. Keep the\n shadow entries within the intended limits so refault tracking does\n not quietly consume more metadata than it should.\n\n - \"selftests/mm: TAP output and global-state fixes\" (Song Hu):\n\n Fix selftests which produce misleading TAP output or fail to restore\n global settings after a run. A test ought to leave the system as it\n found it, particularly when a whole suite follows behind.\n\n - \"mm: remove page_swap_entry()\" (Tal Zussman):\n\n Remove page_swap_entry() and convert its remaining users to the folio\n and swap-entry helpers. Lose an old page-level interface and make the\n swap paths a little more consistent.\n\n - \"mm: refactor zonelist constructors and iterators\" (Gregory Price):\n\n Refactor the zonelist construction and walk helpers to reduce\n duplicated logic. Keep the allocation ordering rules intact while\n making it clearer how zones are selected.\n\n - \"mm: kmemleak: batch the struct page scan\" (Breno Leitao):\n\n Scan adjacent struct pages in batches instead of taking kmemleak_lock\n once for every single page. This preserves scan coverage and the\n lock-hold bound, while cutting overhead substantially on debug\n kernels.\n\n - \"mm/damon: misc improvements in tests and documents\" (Zenghui Yu):\n\n Fix some DAMON selftests which leave kdamond running or fail under\n Python safe-path mode, and improve the KUnit coverage and\n documentation. Nothing especially glamorous, but these are worth\n doing.\n\n - \"mm/damon: introduce probe_hits_wsum DAMOS core filter\" (SJ Park):\n\n Add a DAMOS core filter using weighted probe-hit counts. This gives\n schemes another way to select regions based on what the monitoring\n probes observed.\n\n - \"mm/mglru: fix ineffective memory protection for non-kswapd reclaim\"\n (Ridong Chen):\n\n Fix MGLRU\u0027s memory protection handling for reclaim outside kswapd.\n The protection settings weren\u0027t having the intended effect in these\n paths, leaving protected memory more exposed than requested.\n\n - \"mm/damon: improve readability, clarity and test coverage\" (SJ Park):\n\n Simplify a handful of DAMON core helpers, clarify their behavior and\n expand test coverage. There are no intended userspace-visible changes\n in this batch.\n\n - \"mm: replace PF_KCOMPACTD/PF_KSWAPD with kthread_func()\" (Kefeng\n Wang):\n\n Stop identifying reclaim and compaction workers through the PF_KSWAPD\n and PF_KCOMPACTD task flags. Use their kthread functions instead and\n remove the redundant flag plumbing.\n\n - \"mm/hugetlb: fix surplus accounting and availability checks during\n demotion\" (Longlong Xia):\n\n Fix HugeTLB surplus accounting and availability checks when demoting\n huge pages. Keep the counters and reservation decisions consistent as\n one huge page turns into several smaller ones.\n\n - \"mm/damon: add kunit tests for probe_hits handling and probe params\n validation\" (Jason Angelov):\n\n Add KUnit tests for DAMON probe-hit handling and invalid probe\n parameters. These cover edge cases that were too easy to miss in\n ordinary monitoring tests.\n\n - \"mm/damon: fix misc bugs in kunit, quota goals and sysfs refresh_ms\"\n (SJ Park):\n\n Fix a few DAMON bugs in KUnit tests, quota-goal handling and the\n sysfs refresh interval. Small fixes, but the incorrect results and\n control behavior were real.\n\n - \"mm: zswap: optimize zswap invalidate and store\" (Kefeng Wang):\n\n Simplify zswap\u0027s invalidate and store paths to avoid avoidable\n lookups and work. Keep the entry lifetime rules intact while making\n those frequent operations cheaper.\n\n - \"mm: replace custom ratelimiting logic\" (Pedro Falcato):\n\n Replace hand-rolled MM rate limiting with the common kernel helpers.\n There is no need to maintain another local version of the same\n mechanism.\n\n - \"mm/vmalloc: minor cleanups\" (Ye Liu):\n\n Tidy some vmalloc initialization and reporting code, and pull\n duplicated vmap-area insertion work into a helper. No functional\n changes are intended.\n\n - \"mm/mglru: clean up isolate_folios for readability and clarity\"\n (Ridong Chen):\n\n Clean up MGLRU\u0027s isolate_folios() so the decisions are easier to read\n and verify. Keep reclaim behavior unchanged while removing\n unnecessary twists in the control flow.\n\n - \"Catch automatic storage in IDA and Maple Tree definitions\" (Yury\n Norov):\n\n Catch IDA and maple-tree definitions placed in automatic storage\n where the lifetime rules are wrong or easy to get wrong. Add checks\n so such mistakes are harder to slip through unnoticed.\n\n - \"mm, swap: some random fixes and cleanups\" (Kemeng Shi):\n\n Fix and simplify a few unrelated swap paths, removing redundant work\n and tidying up error handling. A small collection of things which\n were better fixed than left lying around.\n\n - \"mm/page_io: folio conversion cleanups\" (Tal Zussman):\n\n Finish some page-to-folio conversions in swap I/O, removing obsolete\n wrappers and using folio operations consistently. The I/O behavior is\n intended to remain the same.\n\n - \"mm/swap: skip empty clusters in the swapoff scan\" (Youngjun Park):\n\n Skip empty swap clusters during swapoff instead of walking slots\n which have nothing to release. This avoids pointless work on sparsely\n used swap devices.\n\n - \"mm: trace: decode architecture-specific VMA flags\" (Meijing Zhao):\n\n Teach the VMA trace output to decode architecture-specific flags,\n rather than leaving them as unexplained bits. That should make\n tracing a good deal more useful when debugging unusual mappings.\n\n - \"mm, swap: don\u0027t spin on a bad swap entry\" (Breno Leitao):\n\n Stop repeatedly retrying a swap entry which is already known to be\n bad. Make the error path terminate cleanly instead of wasting CPU\n chasing an entry that cannot be used.\n\n - \"mm/page_isolation: fix UBSAN shift-out-of-bounds in\n isolate_single_pageblock\" (Qi Xi):\n\n Fix an out-of-range shift in isolate_single_pageblock() and tighten\n its associated boundary handling. UBSAN found the issue; the result\n should be more robust pageblock isolation.\n\n - \"mm: khugepaged: fix tracepoint UAF\" (Vernon Yang):\n\n Fix a use-after-free in khugepaged tracepoint handling. Make sure the\n information recorded by tracing stays valid for as long as the trace\n event needs it.\n\n - \"mm/damon: fix DAMOS bugs in core, paddr and vaddr\" (SJ Park):\n\n Fix several DAMOS problems across the core and physical- and\n virtual-address backends. The changes close error cases and bring the\n implementations back into agreement.\n\n - \"mm/hugetlb_cgroup: move the per-node usage along with the folio\"\n (Hongfu Li):\n\n Move HugeTLB per-node usage accounting when folios migrate between\n nodes or are reparented to another cgroup. Otherwise numa_stat can\n retain stale charges and even underflow when the folio is freed.\n\n - \"docs/core-api: memory-allocation: add k[mz]alloc_obj() and clarify\n kmalloc\" (Mike Rapoport):\n\n Document the typed k[mz]alloc_obj() allocation helpers and clear up\n some kmalloc guidance. Make it easier for callers to choose the right\n interface.\n\n - \"selftests/mm: Validate selections and scope memfd_secret setup\"\n (Tianyi Chen):\n\n Check selftest selections before running and confine memfd_secret\n setup to the cases that actually need it. Avoid confusing failures\n caused by the test harness itself.\n\n - \"mm/damon: move zero damos quota target_value handling to the core\n layer\" (SJ Park):\n\n Handle a zero DAMOS quota goal target in the core rather than making\n each user of the interface invent its own rule. Keep quota decisions\n consistent across callers.\n\n - \"mm/damon: Introduce a huge page collapsing mechanism using auto\n tuning\" (Asier Gutierrez):\n\n Add an auto-tuned DAMON mechanism for collapsing huge pages. Use\n monitoring feedback to decide when collapse is worthwhile rather than\n forcing one fixed policy onto every workload.\n\n - \"kmemleak: fix stale documentation and raise the verbose default\"\n (Breno Leitao):\n\n Bring the kmemleak documentation up to date and require a third\n confirming scan before verbose kernels print a suspected leak. The\n extra scan helps suppress transient false positives in noisy debug\n builds.\n\n - \"mm/memory: improve insert_pages() error handling\" (Avi Weiss):\n\n Tighten insert_pages() error handling so partial failures are\n reported and cleaned up consistently. The caller should not have to\n guess how far the operation got.\n\n - \"mm/damon: allow NULL or unstarted damon_ctx parameter for\n damon_call()\" (SJ Park):\n\n Make damon_call() handle NULL and not-yet-started contexts safely.\n Simplify the rules for callers and avoid an indefinite wait on an\n invalid state.\n\n - \"mm/damon: introduce pgidle_set probe filter type\" (SJ Park):\n\n Add a pgidle_set DAMON probe filter, giving monitoring users another\n way to select pages by their idle-tracking state. Wire it through the\n filter interfaces and tests.\n\n - \"mm/damon/core: remove unused helper functions\" (Cheng-Han Wu):\n\n Remove DAMON core helpers which no longer have callers. Keep the API\n surface smaller rather than retaining dead code just in case.\n\n - \"mm: stop calling pmd_folio() on special PMDs\" (Gregory Price):\n\n Avoid calling pmd_folio() on special PMD mappings that have no struct\n page. The old assumption could fault in procfs walkers; use the\n normal-folio checks and handle those mappings properly.\n\n - \"mm: remove three unused helpers from mm.h\" (Tal Zussman):\n\n Remove three unused helpers from mm.h. Fewer obsolete interfaces for\n the next person to stumble over.\n\n - \"mm/damon: improvements in efficiency, error handling, documents\"\n (Liew Rui Yan):\n\n Skip needless DAMOS quota work once the quota is full, propagate a\n missing sysfs error and tidy a couple of comments. The ignored error\n could make a monitoring-start request appear successful when it\n wasn\u0027t.\n\n - \"docs/mm/damon/design: add explanation of nr_snapshots\" (Liew Rui\n Yan):\n\n Explain DAMON\u0027s nr_snapshots accounting in the design documentation\n and straighten out the associated terminology. Make it clearer what\n users should expect from that counter.\n\n - \"selftests/cgroup: fixes for test_zswap on single core VM\" (Wilson\n Felipe Pereira):\n\n Fix two test_zswap failures on single-CPU VMs. Wait for the exiting\n child\u0027s cgroup to become unpopulated before reconfiguring it, and\n avoid another test assumption which breaks under constrained\n scheduling.\n\n - \"docs/ksm: fix advisor documentation and comment\" (Jinjiang Tu):\n\n Correct the KSM advisor documentation and a misleading code comment.\n Keep the description aligned with how the advisor actually works.\n\n - \"Fix bugs in HugeTLB allocation when mem_cgroup_charge_hugetlb()\n fails\" (Ackerley Tng):\n\n Fix HugeTLB allocation cleanup when the memcg charge fails. Make sure\n failure exits undo what was allocated rather than leaving stale\n accounting or resources behind.\n\n - \"mm, memcg: fix memory.peak reset clobbering other fds\u0027 watermark\"\n (Ridong Chen):\n\n Fix memory.peak reset handling so resetting one file descriptor\n doesn\u0027t overwrite the watermark kept for another. Keep those per-open\n measurements independent as intended.\n\n - \"mm: reject zone device folios in more folio walkers\" (Gregory\n Price):\n\n Reject zone-device folios in page walkers that cannot safely handle\n them. Extend the existing checks rather than assuming every folio has\n ordinary system-memory backing.\n\n - \"percpu: remove code with no effect\" (Sang-Heon Jeon):\n\n Remove a few pieces of percpu code which no longer do anything. There\n is no reason to keep maintaining dead paths.\n\n* tag \u0027mm-stable-2026-10-19-21-33\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (539 commits)\n mm: shmem: assign a lock class to the unused huge shrinklist\n mm: vmscan: put rotation-missed folios at the LRU tail\n mm: kmemleak: scan the struct page array in MAX_SCAN_SIZE batches\n mm: kmemleak: move the struct page scan into a helper\n mm/damon: document that a zero sample_interval is accepted\n mm/damon: fix typos in comments\n mm/damon/sysfs: propagate damon_call() error in turn_damon_on\n mm/damon/core: skip quota score setup when the quota is full\n mm/damon/tests/core-kunit: test the size charged for a filter-trimmed region\n mm/damon/core: charge only the part of a region the filter left\n mm: disallow raw PFN mappings of huge/shared zeropage\n selftests/mm: zap whole PTE tables in the khugepaged race harness\n selftests/mm: add memory-pressure threads to the khugepaged race harness\n selftests/mm: race the collapse of windows with holes\n selftests/mm: add khugepaged race harness\n selftests/mm: check that one khugepaged pass collapses one window\n selftests/mm: run every supported collapse order by default\n selftests/mm: cover a shared-source collapse write race\n selftests/mm: parameterize the mixed-source collapse case by source order\n selftests/mm: add order-parameterized khugepaged collapse cases\n ...\n" }, { "commit": "cac037a85c1971ec75c4d3edf5a28af9ec2a089c", "tree": "5fa02921c7d4fb5a71edf303c1292d81fa59553a", "parents": [ "ee92b7ef4c1e271b3c1ea2a8b13034bdc62422a7" ], "author": { "name": "Yafang Shao", "email": "laoar.shao@gmail.com", "time": "Fri Oct 23 10:31:04 2026 +0800" }, "committer": { "name": "Peter Zijlstra", "email": "peterz@infradead.org", "time": "Fri Oct 23 19:09:54 2026 +0200" }, "message": "sched: fix stale get_pref_llc() stub for !CONFIG_SCHED_CACHE\n\nCommit b636fef85bda (\"sched/cache: Introduce task_struct-\u003esched_cache_grp\nto fix UAF\") switched get_pref_llc() from taking a struct mm_struct * to\ntaking the task\u0027s struct sched_cache_group *, but only updated the\nCONFIG_SCHED_CACHE definition and its caller: the stub in the\n!CONFIG_SCHED_CACHE branch kept the old mm_struct parameter.\n\nFixes: b636fef85bda (\"sched/cache: Introduce task_struct-\u003esched_cache_grp to fix UAF\")\nSigned-off-by: Yafang Shao \u003claoar.shao@gmail.com\u003e\nSigned-off-by: Peter Zijlstra (Intel) \u003cpeterz@infradead.org\u003e\nReviewed-by: Gregory Price (Meta) \u003cgourry@gourry.net\u003e\nReviewed-by: Chen Yu \u003cyu.c.chen@intel.com\u003e\nReviewed-by: Tim Chen \u003ctim.c.chen@linux.intel.com\u003e\nCc: \u003cstable@vger.kernel.org\u003e #v7.2.x\nLink: https://patch.msgid.link/20261023023105.28829-2-laoar.shao@gmail.com\n" }, { "commit": "ee92b7ef4c1e271b3c1ea2a8b13034bdc62422a7", "tree": "cdd8765212da530402f6c1272aa0ba15c4424120", "parents": [ "7dbc307b6c72a5412e3f4e9fa2e0e926925fc5d6" ], "author": { "name": "Tim Chen", "email": "tim.c.chen@linux.intel.com", "time": "Wed Oct 07 10:25:30 2026 -0700" }, "committer": { "name": "Peter Zijlstra", "email": "peterz@infradead.org", "time": "Fri Oct 23 19:09:54 2026 +0200" }, "message": "sched/cache: Honor asym packing over cache aware scheduling on hybrid systems\n\nA regression was reported on an AMD Ryzen AI HX 370 running a cache\nintensive Clang full-LTO link. The little cores run at a much lower\nfrequency (3.3 GHz vs 5.1 GHz) and have only half of the L3 cache\n(8 MB vs 16 MB), so pinning such a task to the little-core LLC\nhurts twice, and full-LTO builds slow down dramatically compared to\npre-cache-aware-scheduling kernels.\n\nAsym packing and cache aware scheduling express conflicting placement\nstrategies. Asym packing wants a task to run on the highest priority CPU,\nwhereas cache aware scheduling wants to co-locate the tasks of a process\non one LLC regardless of the priority of CPUs in that LLC.\n\nWhen asym packing tries to migrate task to an idle core that has higher\npriority than source cpu, let asym packing win.
