New subject: [PATCH OLK-6.6 v2 01/37] mm: make folios_put() the basis of release_pages()

22 May 2024


      Patch [1-21] is series "Rearrange batched folio freeing" and three bugfix.
Patch [22-26] is series "Clean up __folio_put()".
Patch [27] add trace of alloc_contig_migrate_range.
Patch [28-30] is three bugfix about hugetlb.
Patch [31] is an performance optimization of pcp draining.
Patch [32] is a minor improve of _deferred_list which benefit from debug.
  This patch is from series "Various significant MM patches". Other patches
  are not related to this patch, so don't backport together.
  Patch "mm: Free up PG_slab" may also benefit for us, but have compile
  problem need to fix, so not in this series.
Patch [33-36] is part of series "Improve anon_vma scalability for anon VMAs".
  Patch "mm: Fix some minor per-VMA lock issues in userfaultfd" is not in
  backport because it depends on patch "userfaultfd: use per-vma locks in
  userfaultfd operations"
Patch [37] fix a bug introduced by patch "mm: turn folio_test_hugetlb into
  a PageType" which is from the previous backport.

v1->v2: Add patch [37].
