  mm/damon/sysfs: update monitoring target regions for online input commit (2023-11-01 12:38:35 -0700)

----------------------------------------------------------------
Many singleton patches against the MM code.  The patch series which are
included in this merge do the following:

- Kemeng Shi has contributed some compation maintenance work in the
  series "Fixes and cleanups to compaction".

- Joel Fernandes has a patchset ("Optimize mremap during mutual
  alignment within PMD") which fixes an obscure issue with mremap()'s
  pagetable handling during a subsequent exec(), based upon an
  implementation which Linus suggested.

- More DAMON/DAMOS maintenance and feature work from SeongJae Park i the
  following patch series:

	mm/damon: misc fixups for documents, comments and its tracepoint
	mm/damon: add a tracepoint for damos apply target regions
	mm/damon: provide pseudo-moving sum based access rate
	mm/damon: implement DAMOS apply intervals
	mm/damon/core-test: Fix memory leaks in core-test
	mm/damon/sysfs-schemes: Do DAMOS tried regions update for only one apply interval

- In the series "Do not try to access unaccepted memory" Adrian Hunter
  provides some fixups for the recently-added "unaccepted memory' feature.
  To increase the feature's checking coverage.  "Plug a few gaps where
  RAM is exposed without checking if it is unaccepted memory".

- In the series "cleanups for lockless slab shrink" Qi Zheng has done
  some maintenance work which is preparation for the lockless slab
  shrinking code.

- Qi Zheng has redone the earlier (and reverted) attempt to make slab
  shrinking lockless in the series "use refcount+RCU method to implement
  lockless slab shrink".

- David Hildenbrand contributes some maintenance work for the rmap code
  in the series "Anon rmap cleanups".

- Kefeng Wang does more folio conversions and some maintenance work in
  the migration code.  Series "mm: migrate: more folio conversion and
  unification".

- Matthew Wilcox has fixed an issue in the buffer_head code which was
  causing long stalls under some heavy memory/IO loads.  Some cleanups
  were added on the way.  Series "Add and use bdev_getblk()".

- In the series "Use nth_page() in place of direct struct page
  manipulation" Zi Yan has fixed a potential issue with the direct
  manipulation of hugetlb page frames.

- In the series "mm: hugetlb: Skip initialization of gigantic tail
  struct pages if freed by HVO" has improved our handling of gigantic
  pages in the hugetlb vmmemmep optimizaton code.  This provides
  significant boot time improvements when significant amounts of gigantic
  pages are in use.

- Matthew Wilcox has sent the series "Small hugetlb cleanups" - code
  rationalization and folio conversions in the hugetlb code.

- Yin Fengwei has improved mlock()'s handling of large folios in the
  series "support large folio for mlock"

- In the series "Expose swapcache stat for memcg v1" Liu Shixin has
  added statistics for memcg v1 users which are available (and useful)
  under memcg v2.

- Florent Revest has enhanced the MDWE (Memory-Deny-Write-Executable)
  prctl so that userspace may direct the kernel to not automatically
  propagate the denial to child processes.  The series is named "MDWE
  without inheritance".

- Kefeng Wang has provided the series "mm: convert numa balancing
  functions to use a folio" which does what it says.

- In the series "mm/ksm: add fork-exec support for prctl" Stefan Roesch
  makes is possible for a process to propagate KSM treatment across
  exec().

- Huang Ying has enhanced memory tiering's calculation of memory
  distances.  This is used to permit the dax/kmem driver to use "high
  bandwidth memory" in addition to Optane Data Center Persistent Memory
  Modules (DCPMM).  The series is named "memory tiering: calculate
  abstract distance based on ACPI HMAT"

- In the series "Smart scanning mode for KSM" Stefan Roesch has
  optimized KSM by teaching it to retain and use some historical
  information from previous scans.

- Yosry Ahmed has fixed some inconsistencies in memcg statistics in the
  series "mm: memcg: fix tracking of pending stats updates values".

- In the series "Implement IOCTL to get and optionally clear info about
  PTEs" Peter Xu has added an ioctl to /proc/<pid>/pagemap which permits
  us to atomically read-then-clear page softdirty state.  This is mainly
  used by CRIU.

- Hugh Dickins contributed the series "shmem,tmpfs: general maintenance"
  - a bunch of relatively minor maintenance tweaks to this code.

- Matthew Wilcox has increased the use of the VMA lock over file-backed
  page faults in the series "Handle more faults under the VMA lock".  Some
  rationalizations of the fault path became possible as a result.

- In the series "mm/rmap: convert page_move_anon_rmap() to
  folio_move_anon_rmap()" David Hildenbrand has implemented some cleanups
  and folio conversions.

- In the series "various improvements to the GUP interface" Lorenzo
  Stoakes has simplified and improved the GUP interface with an eye to
  providing groundwork for future improvements.

- Andrey Konovalov has sent along the series "kasan: assorted fixes and
  improvements" which does those things.

- Some page allocator maintenance work from Kemeng Shi in the series
  "Two minor cleanups to break_down_buddy_pages".

- In thes series "New selftest for mm" Breno Leitao has developed
  another MM self test which tickles a race we had between madvise() and
  page faults.

- In the series "Add folio_end_read" Matthew Wilcox provides cleanups
  and an optimization to the core pagecache code.

- Nhat Pham has added memcg accounting for hugetlb memory in the series
  "hugetlb memcg accounting".

- Cleanups and rationalizations to the pagemap code from Lorenzo
  Stoakes, in the series "Abstract vma_merge() and split_vma()".

- Audra Mitchell has fixed issues in the procfs page_owner code's new
  timestamping feature which was causing some misbehaviours.  In the
  series "Fix page_owner's use of free timestamps".

- Lorenzo Stoakes has fixed the handling of new mappings of sealed files
  in the series "permit write-sealed memfd read-only shared mappings".

- Mike Kravetz has optimized the hugetlb vmemmap optimization in the
  series "Batch hugetlb vmemmap modification operations".

- Some buffer_head folio conversions and cleanups from Matthew Wilcox in
  the series "Finish the create_empty_buffers() transition".

- As a page allocator performance optimization Huang Ying has added
  automatic tuning to the allocator's per-cpu-pages feature, in the series
  "mm: PCP high auto-tuning".

- Roman Gushchin has contributed the patchset "mm: improve performance
  of accounted kernel memory allocations" which improves their performance
  by ~30% as measured by a micro-benchmark.

- folio conversions from Kefeng Wang in the series "mm: convert page
  cpupid functions to folios".

- Some kmemleak fixups in Liu Shixin's series "Some bugfix about
  kmemleak".

- Qi Zheng has improved our handling of memoryless nodes by keeping them
  off the allocation fallback list.  This is done in the series "handle
  memoryless nodes more appropriately".

- khugepaged conversions from Vishal Moola in the series "Some
  khugepaged folio conversions".
