left the warning around but as a non-fatal error to get my gcc-15\nbuilds going, but fixed up some of the most annoying warning cases so\nthat it wouldn\u0027t be *too* verbose.\n\nBecause I like the _concept_ of the warning, even if I detested the\nimplementation to shut it up.\n\nIt turns out the implementation to shut it up is even more broken than I\nthought, and my \"shut up most of the warnings\" patch just caused fatal\nerrors on gcc-14 instead.\n\nI had tested with clang, but when I upgrade my development environment,\nI try to do it on all machines because I hate having different systems\nto maintain, and hadn\u0027t realized that gcc-14 now had issues.\n\nThe ACPI case is literally why I wanted to have a *type* that doesn\u0027t\ntrigger the warning (see commit d5d45a7f2619: \"gcc-15: make\n\u0027unterminated string initialization\u0027 just a warning\"), instead of\nmarking individual places as \"__nonstring\".\n\nBut gcc-14 doesn\u0027t like that __nonstring location

a type had failed, because of\nhow gcc doesn\u0027t like marking the types as having attributes, only\nsymbols.\n\nThere may be some trick to it, but I was already annoyed by the bad\nattribute design, now I\u0027m just entirely fed up with it.\n\nI wish gcc had a proper way to say \"this type is a *byte* array, not a\nstring\".\n\nThe obvious thing would be to distinguish between \"char []\" and an\nexplicitly signed \"unsigned char []\" (as opposed to an implicitly\nunsigned char, which is typically an architecture-specific default, but\nfor the kernel is universal thanks to \u0027-funsigned-char\u0027).\n\nBut any \"we can typedef a 8-bit type to not become a string just because\nit\u0027s an array\" model would be fine.\n\nBut \"__attribute__((nonstring))\" is sadly not that sane model.\n\nReported-by: Chris Clayton \u003cchris2553@googlemail.com\u003e\nFixes: 4b4bd8c50f48 (\"gcc-15: acpi: sprinkle random \u0027__nonstring\u0027 crumbles around\")\nFixes:

But it is\nhampered by this bad implementation detail.\n\n[ And obviously I\u0027m doing this now because system upgrades for me are\n something that happen in the middle of the release cycle: don\u0027t do it\n before or during travel, or just before or during the busy merge\n window period. ]\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6fea5fabd3323cd27b2ab5143263f37ff29550cb", "tree": "daf14fe856e36d8023a5ca15db5ea9e96b193fe8", "parents": [ "119009db267415049182774196e3cce9e13b52ef", "ea21641b6a79f9cdd64f8339983c71c89949dcb5" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Apr 19 21:46:58 2025 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Apr 19 21:46:58 2025 -0700" }, "message": "Merge tag \u0027mm-hotfixes-stable-2025-04-19-21-24\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm\n\nPull misc hotfixes from Andrew Morton:\n \"16 hotfixes. 2 are cc:stable and the remainder address post-6.14\n issues or aren\u0027t considered necessary for -stable kernels.\n\n All patches are basically for MM although five are alterations to\n MAINTAINERS\"\n\n[ Basic counting skills are clearly not a strictly necessary requirement\n for kernel maintainers. - Linus ]\n\n* tag \u0027mm-hotfixes-stable-2025-04-19-21-24\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm:\n MAINTAINERS: add section for locking of mm\u0027s and VMAs\n mm: vmscan: fix kswapd exit condition in defrag_mode\n mm: vmscan: restore high-cpu watermark safety in kswapd\n MAINTAINERS: add Pedro as reviewer to the MEMORY MAPPING section\n mm/memory: move sanity checks in do_wp_page() after mapcount vs. refcount stabilization\n mm, hugetlb: increment the number of pages to be reset on HVO\n writeback: fix false warning in inode_to_wb()\n docs: ABI: replace mcroce@microsoft.com with new Meta address\n mm/gup: fix wrongly calculated returned value in fault_in_safe_writeable()\n MAINTAINERS: add memory advice section\n MAINTAINERS: add mmap trace events to MEMORY MAPPING\n mm: memcontrol: fix swap counter leak from offline cgroup\n MAINTAINERS: add MM subsection for the page allocator\n MAINTAINERS: update SLAB ALLOCATOR maintainers\n fs/dax: fix folio splitting issue by resetting old folio order + _nr_pages\n mm/page_alloc: fix deadlock on cpu_hotplug_lock in __accept_page()\n" }, { "commit": "119009db267415049182774196e3cce9e13b52ef", "tree": "5b2f7ccf4b05da5018e2a7f36621126ee45ebd08", "parents": [ "6fe8131757bd58693dba0775e919d46ce183dda2", "408e4504f97c0aa510330f0a04b7ed028fdf3154" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Apr 19 14:31:08 2025 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Apr 19 14:31:08 2025 -0700" }, "message": "Merge tag \u0027vfs-6.15-rc3.fixes.2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs\n\nPull vfs fixes from Christian Brauner:\n\n - Revert the hfs{plus} deprecation warning that\u0027s also included in this\n pull request.

Initialize those\n variables to the EMPTY_HASH, which is the default hash.\n\n - Reinitialize the hash pointers after they are freed\n\n Some of the hash pointers in the subop logic were freed but may still\n be referenced later. To prevent use-after-free bugs, initialize them\n back to the EMPTY_HASH.\n\n - Free the ftrace hashes when they are replaced\n\n The fix that simplified the subops logic updated some hash pointers,\n but left the original hash that they were pointing to where they are\n no longer used. This caused a memory leak. Free the hashes that are\n pointed to by the pointers when they are replaced.\n\n - Fix size initialization of ftrace direct function hash\n\n The ftrace direct function hash used by BPF initialized the hash size\n incorrectly. It checked the size of items to a hard coded 32, which\n made the hash bit size of 5. The hash size is supposed to be limited\n by the bit size of the hash, as the bitmask is allowed to be greater\n than 5. Rework the size check to first pass the number of elements to\n fls() and then compare that to FTRACE_HASH_MAX_BITS before allocating\n the hash.\n\n - Fix format output of ftrace_graph_ent_entry event\n\n The field depth of the ftrace_graph_ent_entry event is of size 4 but\n the output showed it as unsigned long and use \"%lu\". Change it to\n unsigned int and use \"%u\" in the print format that is displayed to\n user space.\n\n - Fix the trace event filter on strings\n\n Events can be filtered on numbers or string values. The return value\n checked from strncpy_from_kernel_nofault() and\n strncpy_from_user_nofault() was used to determine if reading the\n strings would fault or not. It would return fault if the value was\n non zero, which is basically meant that it was always considering the\n read as a fault.\n\n - Add selftest to test trace event string filtering\n\n In order to catch the breakage of the string filtering, add a self\n test to make sure that it continues to work.\n\n* tag \u0027trace-v6.15-rc2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:\n tracing: selftests: Add testing a user string to filters\n tracing: Fix filter string testing\n ftrace: Fix type of ftrace_graph_ent_entry.depth\n ftrace: fix incorrect hash size in register_ftrace_direct()\n ftrace: Free ftrace hashes after they are replaced in the subops code\n ftrace: Reinitialize hash to EMPTY_HASH after freeing\n ftrace: Initialize variables for ftrace_startup/shutdown_subops()\n" }, { "commit": "1ca0f935a126950c2f0b305a50f31f3b00542b0d", "tree": "5fc37286150906c91496371c7165de542904ec65", "parents": [ "0bd2f269ae892ce7283fee8fcfe2c6c971d871bc", "a1d14d931bf700c1025db8c46d6731aa5cf440f9" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Apr 19 10:38:03 2025 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Apr 19 10:38:03 2025 -0700" }, "message": "Merge tag \u0027nfsd-6.15-1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux\n\nPull nfsd fixes from Chuck Lever:\n\n -

However, it cannot (efficiently) meet the contiguity goal of\nsuch a request by itself.

As folio-\u003e_nr_pages overlays\npage[1]-\u003ememcg_data, once page[1] is a folio, it suddenly looks like it\nhas folio-\u003ememcg_data set. And we never manually initialize\nfolio-\u003ememcg_data in fsdax code, because we never expect it to be set at\nall.\n\nWhen __lruvec_stat_mod_folio() then stumbles over such a folio, it tries\nto use folio-\u003ememcg_data (because it\u0027s non-NULL) but it does not actually\npoint at a memcg, resulting in the problem.\n\nAlison also observed that these folios sometimes have \"locked\" set, which\nis rather concerning (folios locked from the beginning ...). The reason\nis that the order for large folios is stored in page[1]-\u003eflags, which\nbecome the folio-\u003eflags of a new small folio.\n\nLet\u0027s fix it by adding a folio helper to clear order/_nr_pages for\nsplitting purposes.\n\nMaybe we should reinitialize other large folio flags / folio members as\nwell when splitting, because they might similarly cause harm once page[1]\nbecomes a folio? At least other flags in PAGE_FLAGS_SECOND should not be\nset for fsdax, so at least page[1]-\u003eflags might be as expected with this\nfix.\n\nFrom a quick glimpse, initializing -\u003emapping, -\u003epgmap and -\u003eshare should\nre-initialize most things from a previous page[1] used by large folios\nthat fsdax cares about. For example folio-\u003eprivate might not get\nreinitialized, but maybe that\u0027s not relevant -- no traces of it\u0027s use in\nfsdax code. Needs a closer look.\n\nAnother thing that should be considered in the future is performing\nsimilar checks as we perform in free_tail_page_prepare()\n-- checking pincount etc.\n-- when freeing a large fsdax folio.\n\nLink: https://lkml.kernel.org/r/20250410091020.119116-1-david@redhat.com\nFixes: 4996fc547f5b (\"mm: let _folio_nr_pages overlay memcg_data in first tail page\")\nFixes: 38607c62b34b (\"fs/dax: properly refcount fs dax pages\")\nSigned-off-by: David Hildenbrand \u003cdavid@redhat.com\u003e\nReported-by: Alison Schofield \u003calison.schofield@intel.com\u003e\nCloses: https://lkml.kernel.org/r/Z_W9Oeg-D9FhImf3@aschofie-mobl2.lan\nTested-by: Alison Schofield \u003calison.schofield@intel.com\u003e\nReviewed-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\nTested-by: \"Darrick J.
