Instead of jumping to this out\n label, simply return immediately and remove the out label.\n\n - Add guard(ring_buffer_nest)\n\n Some calls to the tracing ring buffer can happen when the ring buffer\n is already being written to at the same context (for example, a\n trace_printk() in between a ring_buffer_lock_reserve() and a\n ring_buffer_unlock_commit()).\n\n In order to not trigger the recursion detection, these functions use\n ring_buffer_nest_start() and ring_buffer_nest_end(). Create a guard()\n for these functions so that their use cases can be simplified and not\n need to use goto for the release.\n\n - Clean up the tracing code with guard() and __free() logic\n\n There were several locations that were prime candidates for using\n guard() and __free() helpers. Switch them over to use them.\n\n - Fix output of function argument traces for unsigned int values\n\n The function tracer with \"func-args\" option set will record up to 6\n argument registers and then use BTF to format them for human\n consumption when the trace file is read.

Enable a set of Clippy lints: \u0027ptr_as_ptr\u0027, \u0027ptr_cast_constness\u0027,\n \u0027as_ptr_cast_mut\u0027, \u0027as_underscore\u0027, \u0027cast_lossless\u0027 and\n \u0027ref_as_ptr\u0027\n\n These are intended to avoid type casts with the \u0027as\u0027 operator,\n which are quite powerful, into restricted variants that are less\n powerful and thus should help to avoid mistakes\n\n - Remove the \u0027author\u0027 key now that most instances were moved to the\n plural one in the previous cycle\n\n \u0027kernel\u0027 crate:\n\n - New \u0027bug\u0027 module: add \u0027warn_on!\u0027 macro which reuses the existing\n \u0027BUG\u0027/\u0027WARN\u0027 infrastructure, i.e. it respects the usual sysctls and\n kernel parameters:\n\n warn_on!(value \u003d\u003d 42);\n\n To avoid duplicating the assembly code, the same strategy is\n followed as for the static branch code in order to share the\n assembly between both C and Rust\n\n This required a few rearrangements on C arch headers -- the\n existing C macros should still generate the same outputs, thus no\n functional change expected there\n\n - \u0027workqueue\u0027 module: add delayed work items, including a\n \u0027DelayedWork\u0027 struct, a \u0027impl_has_delayed_work!\u0027 macro and an\n \u0027enqueue_delayed\u0027 method, e.g.:\n\n /// Enqueue the struct for execution on the system workqueue,\n /// where its value will be printed 42 jiffies later.\n fn print_later(value: Arc\u003cMyStruct\u003e) {\n let _ \u003d workqueue::system().enqueue_delayed(value, 42);\n }\n\n - New \u0027bits\u0027 module: add support for \u0027bit\u0027 and \u0027genmask\u0027 functions,\n with runtime- and compile-time variants, e.g.:\n\n static_assert!(0b00010000 \u003d\u003d bit_u8(4));\n static_assert!(0b00011110 \u003d\u003d genmask_u8(1..\u003d4));\n\n assert!(checked_bit_u32(u32::BITS).is_none());\n\n - \u0027uaccess\u0027 module: add \u0027UserSliceReader::strcpy_into_buf\u0027, which\n reads NUL-terminated strings from userspace into a \u0027\u0026CStr\u0027\n\n Introduce \u0027UserPtr\u0027 newtype, similar in purpose to \u0027__user\u0027 in C,\n to minimize mistakes handling userspace pointers, including mixing\n them up with integers and leaking them via the \u0027Debug\u0027 trait. Add\n it to the prelude, too\n\n - Start preparations for the replacement of our custom \u0027CStr\u0027 type\n with the analogous type in the \u0027core\u0027 standard library. This will\n take place across several cycles to make it easier. For this one,\n it includes a new \u0027fmt\u0027 module, using upstream method names and\n some other cleanups\n\n Replace \u0027fmt!\u0027 with a re-export, which helps Clippy lint properly,\n and clean up the found \u0027uninlined-format-args\u0027 instances\n\n - \u0027dma\u0027 module:\n\n - Clarify wording and be consistent in \u0027coherent\u0027 nomenclature\n\n - Convert the \u0027read!()\u0027 and \u0027write!()\u0027 macros to return a \u0027Result\u0027\n\n - Add \u0027as_slice()\u0027, \u0027write()\u0027 methods in \u0027CoherentAllocation\u0027\n\n - Expose \u0027count()\u0027 and \u0027size()\u0027 in \u0027CoherentAllocation\u0027 and add\n the corresponding type invariants\n\n - Implement \u0027CoherentAllocation::dma_handle_with_offset()\u0027\n\n - \u0027time\u0027 module:\n\n - Make \u0027Instant\u0027 generic over clock source. This allows the\n compiler to assert that arithmetic expressions involving the\n \u0027Instant\u0027 use \u0027Instants\u0027 based on the same clock source\n\n - Make \u0027HrTimer\u0027 generic over the timer mode. \u0027HrTimer\u0027 timers\n take a \u0027Duration\u0027 or an \u0027Instant\u0027 when setting the expiry time,\n depending on the timer mode. With this change, the compiler can\n check the type matches the timer mode\n\n - Add an abstraction for \u0027fsleep\u0027. \u0027fsleep\u0027 is a flexible sleep\n function that will select an appropriate sleep method depending\n on the requested sleep time\n\n - Avoid 64-bit divisions on 32-bit hardware when calculating\n timestamps\n\n - Seal the \u0027HrTimerMode\u0027 trait. This prevents users of the\n \u0027HrTimerMode\u0027 from implementing the trait on their own types\n\n - Pass the correct timer mode ID to \u0027hrtimer_start_range_ns()\u0027\n\n - \u0027list\u0027 module: remove \u0027OFFSET\u0027 constants, allowing to remove\n pointer arithmetic; now \u0027impl_list_item!\u0027 invokes\n \u0027impl_has_list_links!\u0027 or \u0027impl_has_list_links_self_ptr!\u0027. Other\n simplifications too\n\n - \u0027types\u0027 module: remove \u0027ForeignOwnable::PointedTo\u0027 in favor of a\n constant, which avoids exposing the type of the opaque pointer, and\n require \u0027into_foreign\u0027 to return non-null\n\n Remove the \u0027Either\u003cL, R\u003e\u0027 type as well. It is unused, and we want\n to encourage the use of custom enums for concrete use cases\n\n - \u0027sync\u0027 module: implement \u0027Borrow\u0027 and \u0027BorrowMut\u0027 for \u0027Arc\u0027 types\n to allow them to be used in generic APIs\n\n - \u0027alloc\u0027 module: implement \u0027Borrow\u0027 and \u0027BorrowMut\u0027 for \u0027Box\u003cT, A\u003e\u0027;\n and \u0027Borrow\u0027, \u0027BorrowMut\u0027 and \u0027Default\u0027 for \u0027Vec\u003cT, A\u003e\u0027\n\n - \u0027Opaque\u0027 type: add \u0027cast_from\u0027 method to perform a restricted cast\n that cannot change the inner type and use it in callers of\n \u0027container_of!\u0027. Rename \u0027raw_get\u0027 to \u0027cast_into\u0027 to match it\n\n - \u0027rbtree\u0027 module: add \u0027is_empty\u0027 method\n\n - \u0027sync\u0027 module: new \u0027aref\u0027 submodule to hold \u0027AlwaysRefCounted\u0027 and\n \u0027ARef\u0027, which are moved from the too general \u0027types\u0027 module which\n we want to reduce or eventually remove. Also fix a safety comment\n in \u0027static_lock_class\u0027\n\n \u0027pin-init\u0027 crate:\n\n - Add \u0027impl\u003cT, E\u003e [Pin]Init\u003cT, E\u003e for Result\u003cT, E\u003e\u0027, so results are\n now (pin-)initializers\n\n - Add \u0027Zeroable::init_zeroed()\u0027 that delegates to \u0027init_zeroed()\u0027\n\n - New \u0027zeroed()\u0027, a safe version of \u0027mem::zeroed()\u0027 and also provide\n it via \u0027Zeroable::zeroed()\u0027\n\n - Implement \u0027Zeroable\u0027 for \u0027Option\u003c\u0026T\u003e\u0027, \u0027Option\u003c\u0026mut T\u003e\u0027 and for\n \u0027Option\u003c[unsafe] [extern \"abi\"] fn(...args...) -\u003e ret\u003e\u0027 for\n \u0027\"Rust\"\u0027 and \u0027\"C\"\u0027 ABIs and up to 20 arguments\n\n - Changed blanket impls of \u0027Init\u0027 and \u0027PinInit\u0027 from \u0027impl\u003cT, E\u003e\n [Pin]Init\u003cT, E\u003e for T\u0027 to \u0027impl\u003cT\u003e [Pin]Init\u003cT\u003e for T\u0027\n\n - Renamed \u0027zeroed()\u0027 to \u0027init_zeroed()\u0027\n\n - Upstream dev news: improve CI more to deny warnings, use\n \u0027--all-targets\u0027.

Currently, folios are isolated and added to the\nlist even if they are already in the node they should be in.\n\nIn using damon weighted interleave more, I\u0027ve found that the overhead of\nneedlessly adding these folios to the migration lists can be quite high. \nThe overhead comes from isolating folios and placing them in the migration\nlists inside of damos_va_migrate_dests_add(), as well as the cost of\nhandling those folios in damon_migrate_pages(). This patch eliminates\nthat overhead by simply avoiding the addition of folios that are already\nin their intended location to the migration list.\n\nTo show the benefit of this patch, we start the test workload and start a\nDAMON instance attached to that workload with a migrate_hot scheme that\nhas one dest field sending data to the local node. This way, we are only\nmeasuring the overheads of the scheme, and not the cost of migrating\npages, since data will be allocated to the local node by default. I\ntested with two workloads: the embedding reduction workload used in [1]\nand a microbenchmark that allocates 20GB of data then sleeps, which is\nsimilar to the memory usage of the embedding reduction workload.\n\nThe time taken in damos_va_migrate_dests_add() and damon_migrate_pages()\neach aggregation interval is shown below.\n\nBefore this patch:\n damos_va_migrate_dests_add damon_migrate_pages\nmicrobenchmark ~2ms ~3ms\nembedding reduction ~1s ~3s\n\nAfter this patch:\n damos_va_migrate_dests_add damon_migrate_pages\nmicrobenchmark 0us ~40us\nembedding reduction 0us ~100us\n\nI did not do an in depth analysis for why things are much slower in the\nembedding reduction workload than the microbenchmark. However, I assume\nit\u0027s because the embedding reduction workload oversaturates the bandwidth\nof the local memory node, increasing the memory access latency, and in\nturn making the pointer chasing involved in iterating through a linked\nlist much slower.

We can not put them there before, because chances are pretty\ngood that at least some page in the target range is already in use by the\ncurrently running Linux environment. Copying is happening from a single\nCPU at RAM rate, which takes around 4-50 ms per 100 MiB.\n\nAll of this is inefficient and error prone.\n\nTo successfully kexec, we need to quiesce all devices of the outgoing\nkernel so they don\u0027t scribble over the new kernel\u0027s memory. We have seen\ncases where that does not happen properly (*cough* GIC *cough*) and hence\nthe new kernel was corrupted. This started a month long journey to root\ncause failing kexecs to eventually see memory corruption, because the new\nkernel was corrupted severely enough that it could not emit output to tell\nus about the fact that it was corrupted. By allocating memory for the\nnext kernel from a memory range that is guaranteed scribbling free, we can\nboot the next kernel up to a point where it is at least able to detect\ncorruption and maybe even stop it before it becomes severe. This\nincreases the chance for successful kexecs.\n\nSince kexec got introduced, Linux has gained the CMA framework which can\nperform physically contiguous memory mappings, while keeping that memory\navailable for movable memory when it is not needed for contiguous\nallocations. The default CMA allocator is for DMA allocations.\n\nThis patch adds logic to the kexec file loader to attempt to place the\ntarget payload at a location allocated from CMA. If successful, it uses\nthat memory range directly instead of creating copy instructions during\nthe hot phase. To ensure that there is a safety net in case anything goes\nwrong with the CMA allocation, it also adds a flag for user space to force\ndisable CMA allocations.\n\nUsing CMA allocations has two advantages:\n\n 1) Faster by 4-50 ms per 100 MiB.

The\n`xa_get_order(\u0026mapping-\u003ei_pages, index) !\u003d folio_order(folio)` will always\nreturn false causing swap-in to return -EEXIST.\n\nAnd this looks fragile. So fix this up by allowing seeing a larger folio\nin swap cache, and check the whole shmem mapping range covered by the\nswapin have the right swap value upon inserting the folio. And drop the\nredundant tree walks before the insertion.\n\nThis will actually improve performance, as it avoids two redundant Xarray\ntree walks in the hot path, and the only side effect is that in the\nfailure path, shmem may redundantly reallocate a few folios causing\ntemporary slight memory pressure.\n\nAnd worth noting, it may seems the order and value check before inserting\nmight help reducing the lock contention, which is not true. The swap\ncache layer ensures raced swapin will either see a swap cache folio or\nfailed to do a swapin (we have SWAP_HAS_CACHE bit even if swap cache is\nbypassed), so holding the folio lock and checking the folio flag is\nalready good enough for avoiding the lock contention. The chance that a\nfolio passes the swap entry value check but the shmem mapping slot has\nchanged should be very low.\n\nLink: https://lkml.kernel.org/r/20250728075306.12704-1-ryncsn@gmail.com\nLink: https://lkml.kernel.org/r/20250728075306.12704-2-ryncsn@gmail.com\nFixes: 809bc86517cc (\"mm: shmem: support large folio swap out\")\nSigned-off-by: Kairui Song \u003ckasong@tencent.com\u003e\nReviewed-by: Kemeng Shi \u003cshikemeng@huaweicloud.com\u003e\nReviewed-by: Baolin Wang \u003cbaolin.wang@linux.alibaba.com\u003e\nTested-by: Baolin Wang \u003cbaolin.wang@linux.alibaba.com\u003e\nCc: Baoquan He \u003cbhe@redhat.com\u003e\nCc: Barry Song \u003cbaohua@kernel.org\u003e\nCc: Chris Li \u003cchrisl@kernel.org\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nCc: Matthew Wilcox (Oracle) \u003cwilly@infradead.org\u003e\nCc: Nhat Pham \u003cnphamcs@gmail.com\u003e\nCc: Dev Jain \u003cdev.jain@arm.com\u003e\nCc: \u003cstable@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\n" }, { "commit": "eacf91b0c78a7113844830ed65ebf543eb9052c5", "tree": "b45f7a1364ca39503cd252fd434f394a69324925", "parents": [ "7061835997daba9e73c723c85bd70bc4c44aef77", "81b96e4aef9592493873507eec52eca68f0721ac" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Aug 02 09:58:11 2025 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Aug 02 09:58:11 2025 -0700" }, "message": "Merge tag \u0027fbdev-for-6.17-rc1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/deller/linux-fbdev\n\nPull fbdev updates from Helge Deller:\n \"One potential buffer overflow fix in the framebuffer registration\n function, some fixes for the imxfb, nvidiafb and simplefb drivers, and\n a bunch of cleanups for fbcon, kyrofb and svgalib.\n\n Framework fixes:\n - fix potential buffer overflow in do_register_framebuffer() [Yongzhen Zhang]\n\n Driver fixes:\n - imxfb: prevent null-ptr-deref [Chenyuan Yang]\n - nvidiafb: fix build on 32-bit ARCH\u003dum [Johannes Berg]\n - nvidiafb: add depends on HAS_IOPORT [Randy Dunlap]\n - simplefb: Use of_reserved_mem_region_to_resource() for \"memory-region\" [Rob Herring]\n\n Cleanups:\n - fbcon: various code cleanups wrt blinking [Ville Syrjälä]\n - kyrofb: Convert to devm_*() functions [Giovanni Di Santi]\n - svgalib: Coding style cleanups [Darshan R.]\n - Fix typo in Kconfig text for FB_DEVICE [Daniel Palmer]\"\n\n* tag \u0027fbdev-for-6.17-rc1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/deller/linux-fbdev:\n fbcon: Use \u0027bool\u0027 where appopriate\n fbcon: Introduce get_{fg,bg}_color()\n fbcon: fbcon_is_inactive() -\u003e fbcon_is_active()\n fbcon: fbcon_cursor_noblink -\u003e fbcon_cursor_blink\n fbdev: Fix typo in Kconfig text for FB_DEVICE\n fbdev: imxfb: Check fb_add_videomode to prevent null-ptr-deref\n fbdev: svgalib: Clean up coding style\n fbdev: kyro: Use devm_ioremap_wc() for screen mem\n fbdev: kyro: Use devm_ioremap() for mmio registers\n fbdev: kyro: Add missing PCI memory region request\n fbdev: simplefb: Use of_reserved_mem_region_to_resource() for \"memory-region\"\n fbdev: fix potential buffer overflow in do_register_framebuffer()\n fbdev: nvidiafb: add depends on HAS_IOPORT\n fbdev: nvidiafb: fix build on 32-bit ARCH\u003dum\n" } ], "next": "7061835997daba9e73c723c85bd70bc4c44aef77" }
