<torvalds@linux-foundation.org> # Date: Sun May 19 09:21:03 2024 -0700 # # Merge tag 'mm-stable-2024-05-17-19-19' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm # # Pull mm updates from Andrew Morton: # "The usual shower of singleton fixes and minor series all over MM, # documented (hopefully adequately) in the respective changelogs. # Notable series include: # # - Lucas Stach has provided some page-mapping cleanup/consolidation/ # maintainability work in the series "mm/treewide: Remove pXd_huge() # API". # # - In the series "Allow migrate on protnone reference with # MPOL_PREFERRED_MANY policy", Donet Tom has optimized mempolicy's # MPOL_PREFERRED_MANY mode, yielding almost doubled performance in # one test. # # - In their series "Memory allocation profiling" Kent Overstreet and # Suren Baghdasaryan have contributed a means of determining (via # /proc/allocinfo) whereabouts in the kernel memory is being # allocated: number of calls and amount of memory. # # - Matthew Wilcox has provided the series "Various significant MM # patches" which does a number of rather unrelated things, but in # largely similar code sites. # # - In his series "mm: page_alloc: freelist migratetype hygiene" # Johannes Weiner has fixed the page allocator's handling of # migratetype requests, with resulting improvements in compaction # efficiency. # # - In the series "make the hugetlb migration strategy consistent" # Baolin Wang has fixed a hugetlb migration issue, which should # improve hugetlb allocation reliability. # # - Liu Shixin has hit an I/O meltdown caused by readahead in a # memory-tight memcg. Addressed in the series "Fix I/O high when # memory almost met memcg limit". # # - In the series "mm/filemap: optimize folio adding and splitting" # Kairui Song has optimized pagecache insertion, yielding ~10% # performance improvement in one test. # # - Baoquan He has cleaned up and consolidated the early zone # initialization code in the series "mm/mm_init.c: refactor # free_area_init_core()". # # - Baoquan has also redone some MM initializatio code in the series # "mm/init: minor clean up and improvement". # # - MM helper cleanups from Christoph Hellwig in his series "remove # follow_pfn". # # - More cleanups from Matthew Wilcox in the series "Various # page->flags cleanups". # # - Vlastimil Babka has contributed maintainability improvements in the # series "memcg_kmem hooks refactoring". # # - More folio conversions and cleanups in Matthew Wilcox's series: # "Convert huge_zero_page to huge_zero_folio" # "khugepaged folio conversions" # "Remove page_idle and page_young wrappers" # "Use folio APIs in procfs" # "Clean up __folio_put()" # "Some cleanups for memory-failure" # "Remove page_mapping()" # "More folio compat code removal" # # - David Hildenbrand chipped in with "fs/proc/task_mmu: convert # hugetlb functions to work on folis". # # - Code consolidation and cleanup work related to GUP's handling of # hugetlbs in Peter Xu's series "mm/gup: Unify hugetlb, part 2". # # - Rick Edgecombe has developed some fixes to stack guard gaps in the # series "Cover a guard gap corner case". # # - Jinjiang Tu has fixed KSM's behaviour after a fork+exec in the # series "mm/ksm: fix ksm exec support for prctl". # # - Baolin Wang has implemented NUMA balancing for multi-size THPs. # This is a simple first-cut implementation for now. The series is # "support multi-size THP numa balancing". # # - Cleanups to vma handling helper functions from Matthew Wilcox in # the series "Unify vma_address and vma_pgoff_address". # # - Some selftests maintenance work from Dev Jain in the series # "selftests/mm: mremap_test: Optimizations and style fixes". # # - Improvements to the swapping of multi-size THPs from Ryan Roberts # in the series "Swap-out mTHP without splitting". # # - Kefeng Wang has significantly optimized the handling of arm64's # permission page faults in the series # "arch/mm/fault: accelerate pagefault when badaccess" # "mm: remove arch's private VM_FAULT_BADMAP/BADACCESS" # # - GUP cleanups from David Hildenbrand in "mm/gup: consistently call # it GUP-fast". # # - hugetlb fault code cleanups from Vishal Moola in "Hugetlb fault # path to use struct vm_fault". # # - selftests build fixes from John Hubbard in the series "Fix # selftests/mm build without requiring "make headers"". # # - Memory tiering fixes/improvements from Ho-Ren (Jack) Chuang in the # series "Improved Memory Tier Creation for CPUless NUMA Nodes". # Fixes the initialization code so that migration between different # memory types works as intended. # # - David Hildenbrand has improved follow_pte() and fixed an errant # driver in the series "mm: follow_pte() improvements and acrn # follow_pte() fixes". # # - David also did some cleanup work on large folio mapcounts in his # series "mm: mapcount for large folios + page_mapcount() cleanups". # # - Folio conversions in KSM in Alex Shi's series "transfer page to # folio in KSM". # # - Barry Song has added some sysfs stats for monitoring multi-size # THP's in the series "mm: add per-order mTHP alloc and swpout # counters". # # - Some zswap cleanups from Yosry Ahmed in the series "zswap # same-filled and limit checking cleanups". # # - Matthew Wilcox has been looking at buffer_head code and found the # documentation to be lacking. The series is "Improve buffer head # documentation". # # - Multi-size THPs get more work, this time from Lance Yang. His # series "mm/madvise: enhance lazyfreeing with mTHP in madvise_free" # optimizes the freeing of these things. # # - Kemeng Shi has added more userspace-visible writeback # instrumentation in the series "Improve visibility of writeback". # # - Kemeng Shi then sent some maintenance work on top in the series # "Fix and cleanups to page-writeback". # # - Matthew Wilcox reduces mmap_lock traffic in the anon vma code in # the series "Improve anon_vma scalability for anon VMAs". Intel's # test bot reported an improbable 3x improvement in one test. # # - SeongJae Park adds some DAMON feature work in the series # "mm/damon: add a DAMOS filter type for page granularity access recheck" # "selftests/damon: add DAMOS quota goal test" # # - Also some maintenance work in the series # "mm/damon/paddr: simplify page level access re-check for pageout" # "mm/damon: misc fixes and improvements" # # - David Hildenbrand has disabled some known-to-fail selftests ni the # series "selftests: mm: cow: flag vmsplice() hugetlb tests as # XFAIL". # # - memcg metadata storage optimizations from Shakeel Butt in "memcg: # reduce memory consumption by memcg stats". # # - DAX fixes and maintenance work from Vishal Verma in the series # "dax/bus.c: Fixups for dax-bus locking""
