Linus, please merge this cycle's MM updates. I'm presently seeing one merge conflict in fs/buffer.c. Stephen's resolution is described at https://lkml.kernel.org/r/20230110132519.72181341@xxxxxxxxxxxxxxxx. There are a lot of conflicts in your future, mainly because of the ongoing folio conversion work. This will hopefully come to an end fairly soon. Forthcoming conflicts which are known about, along with Stephen's fixes are: Documentation/admin-guide/cgroup-v1/memory.rst https://lkml.kernel.org/r/20230106125915.60c8b547@xxxxxxxxxxxxxxxx drivers/infiniband/hw/hfi1/file_ops.c https://lkml.kernel.org/r/20230127162143.1a3bc64b@xxxxxxxxxxxxxxxx drivers/gpu/drm/i810/i810_dma.c https://lkml.kernel.org/r/20230127162426.19daa5b1@xxxxxxxxxxxxxxxx drivers/staging/media/deprecated/meye/meye.c https://lkml.kernel.org/r/20230127162647.037701db@xxxxxxxxxxxxxxxx drivers/staging/media/deprecated/stkwebcam/stk-webcam.c https://lkml.kernel.org/r/20230127162906.77e540fa@xxxxxxxxxxxxxxxx Documentation/admin-guide/mm/numaperf.rst https://lkml.kernel.org/r/20230209131258.1d7a28fb@xxxxxxxxxxxxxxxx Documentation/translations/zh_CN/accounting/delay-accounting.rst https://lkml.kernel.org/r/20230214133929.7d8ed00f@xxxxxxxxxxxxxxxx include/linux/memcontrol.h mm/memcontrol.c https://lkml.kernel.org/r/20230215135734.4dffcd39@xxxxxxxxxxxxxxxx fs/nfs/write.c https://lkml.kernel.org/r/20230216140514.631bcca1@xxxxxxxxxxxxxxxx fs/cifs/file.c https://lkml.kernel.org/r/20230220152933.1ab8fa4a@xxxxxxxxxxxxxxxx fs/ext4/inode.c https://lkml.kernel.org/r/20230220152938.45f62d5a@xxxxxxxxxxxxxxxx Thanks. The following changes since commit 1301f9313484f9eeb09904988b2aabd398492797: Pull mm-hotfixes-stable dependencies into mm-stable. (2023-01-18 17:03:20 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm tags/mm-stable-2023-02-20-13-37 for you to fetch changes up to f9366f4c2a29d14f5992b195e268240c2deb116e: include/linux/migrate.h: remove unneeded externs (2023-02-20 12:46:18 -0800) ---------------------------------------------------------------- - Daniel Verkamp has contributed a memfd series ("mm/memfd: add F_SEAL_EXEC") which permits the setting of the memfd execute bit at memfd creation time, with the option of sealing the state of the X bit. - Peter Xu adds a patch series ("mm/hugetlb: Make huge_pte_offset() thread-safe for pmd unshare") which addresses a rare race condition related to PMD unsharing. - Several folioification patch serieses from Matthew Wilcox, Vishal Moola, Sidhartha Kumar and Lorenzo Stoakes - Johannes Weiner has a series ("mm: push down lock_page_memcg()") which does perform some memcg maintenance and cleanup work. - SeongJae Park has added DAMOS filtering to DAMON, with the series "mm/damon/core: implement damos filter". These filters provide users with finer-grained control over DAMOS's actions. SeongJae has also done some DAMON cleanup work. - Kairui Song adds a series ("Clean up and fixes for swap"). - Vernon Yang contributed the series "Clean up and refinement for maple tree". - Yu Zhao has contributed the "mm: multi-gen LRU: memcg LRU" series. It adds to MGLRU an LRU of memcgs, to improve the scalability of global reclaim. - David Hildenbrand has added some userfaultfd cleanup work in the series "mm: uffd-wp + change_protection() cleanups". - Christoph Hellwig has removed the generic_writepages() library function in the series "remove generic_writepages". - Baolin Wang has performed some maintenance on the compaction code in his series "Some small improvements for compaction". - Sidhartha Kumar is doing some maintenance work on struct page in his series "Get rid of tail page fields". - David Hildenbrand contributed some cleanup, bugfixing and generalization of pte management and of pte debugging in his series "mm: support __HAVE_ARCH_PTE_SWP_EXCLUSIVE on all architectures with swap PTEs". - Mel Gorman and Neil Brown have removed the __GFP_ATOMIC allocation flag in the series "Discard __GFP_ATOMIC". - Sergey Senozhatsky has improved zsmalloc's memory utilization with his series "zsmalloc: make zspage chain size configurable". - Joey Gouly has added prctl() support for prohibiting the creation of writeable+executable mappings. The previous BPF-based approach had shortcomings. See "mm: In-kernel support for memory-deny-write-execute (MDWE)". - Waiman Long did some kmemleak cleanup and bugfixing in the series "mm/kmemleak: Simplify kmemleak_cond_resched() & fix UAF". - T.J. Alumbaugh has contributed some MGLRU cleanup work in his series "mm: multi-gen LRU: improve". - Jiaqi Yan has provided some enhancements to our memory error statistics reporting, mainly by presenting the statistics on a per-node basis. See the series "Introduce per NUMA node memory error statistics". - Mel Gorman has a second and hopefully final shot at fixing a CPU-hog regression in compaction via his series "Fix excessive CPU usage during compaction". - Christoph Hellwig does some vmalloc maintenance work in the series "cleanup vfree and vunmap". - Christoph Hellwig has removed block_device_operations.rw_page() in ths series "remove ->rw_page". - We get some maple_tree improvements and cleanups in Liam Howlett's series "VMA tree type safety and remove __vma_adjust()". - Suren Baghdasaryan has done some work on the maintainability of our vm_flags handling in the series "introduce vm_flags modifier functions". - Some pagemap cleanup and generalization work in Mike Rapoport's series "mm, arch: add generic implementation of pfn_valid() for FLATMEM" and "fixups for generic implementation of pfn_valid()" - Baoquan He has done some work to make /proc/vmallocinfo and /proc/kcore better represent the real state of things in his series "mm/vmalloc.c: allow vread() to read out vm_map_ram areas". - Jason Gunthorpe rationalized the GUP system's interface to the rest of the kernel in the series "Simplify the external interface for GUP". - SeongJae Park wishes to migrate people from DAMON's debugfs interface over to its sysfs interface. To support this, we'll temporarily be printing warnings when people use the debugfs interface. See the series "mm/damon: deprecate DAMON debugfs interface". - Andrey Konovalov provided the accurately named "lib/stackdepot: fixes and clean-ups" series. - Huang Ying has provided a dramatic reduction in migration's TLB flush IPI rates with the series "migrate_pages(): batch TLB flushing". - Arnd Bergmann has some objtool fixups in "objtool warning fixes".
