  mm/hugetlb: remove hugetlb_set_page_subpool() (2023-06-23 16:59:33 -0700)

----------------------------------------------------------------
- Yosry Ahmed brought back some cgroup v1 stats in OOM logs.

- Yosry has also eliminated cgroup's atomic rstat flushing.

- Nhat Pham adds the new cachestat() syscall.  It provides userspace
  with the ability to query pagecache status - a similar concept to
  mincore() but more powerful and with improved usability.

- Mel Gorman provides more optimizations for compaction, reducing the
  prevalence of page rescanning.

- Lorenzo Stoakes has done some maintanance work on the get_user_pages()
  interface.

- Liam Howlett continues with cleanups and maintenance work to the maple
  tree code.  Peng Zhang also does some work on maple tree.

- Johannes Weiner has done some cleanup work on the compaction code.

- David Hildenbrand has contributed additional selftests for
  get_user_pages().

- Thomas Gleixner has contributed some maintenance and optimization work
  for the vmalloc code.

- Baolin Wang has provided some compaction cleanups,

- SeongJae Park continues maintenance work on the DAMON code.

- Huang Ying has done some maintenance on the swap code's usage of
  device refcounting.

- Christoph Hellwig has some cleanups for the filemap/directio code.

- Ryan Roberts provides two patch series which yield some
  rationalization of the kernel's access to pte entries - use the provided
  APIs rather than open-coding accesses.

- Lorenzo Stoakes has some fixes to the interaction between pagecache
  and directio access to file mappings.

- John Hubbard has a series of fixes to the MM selftesting code.

- ZhangPeng continues the folio conversion campaign.

- Hugh Dickins has been working on the pagetable handling code, mainly
  with a view to reducing the load on the mmap_lock.

- Catalin Marinas has reduced the arm64 kmalloc() minimum alignment from
  128 to 8.

- Domenico Cerasuolo has improved the zswap reclaim mechanism by
  reorganizing the LRU management.

- Matthew Wilcox provides some fixups to make gfs2 work better with the
  buffer_head code.

- Vishal Moola also has done some folio conversion work.

- Matthew Wilcox has removed the remnants of the pagevec code - their
  functionality is migrated over to struct folio_batch.
