  mm/vma: predicate setting mmap_prepare VMA fields on new vma alloc (2026-09-26 13:55:11 -0700)

----------------------------------------------------------------
10 hotfixes.  5 are cc:stable.

- Fix module loading incorrectly returning success after alloc_tag codetag
  setup failed.

- Restore MADV_COLLAPSE semantics for shmem so forced collapse ignores the
  shmem THP/mTHP sysfs settings.

- Make alloc_tag UAPI structure padding explicit.

- Fix DAMON schemes unexpectedly stopping after quotas are disabled through
  the online parameter update interface.

- Fix a false SW_TAGS KASAN invalid-access report when freeing vmapped task
  stacks.

- Split the MEMORY MANAGEMENT - MEMORY POLICY AND MIGRATION MAINTAINERS
  entry into separate MIGRATION and NUMA PLACEMENT entries.

- Move memory tiering maintenance under NUMA PLACEMENT.

- Add Gregory Price as a NUMA PLACEMENT co-maintainer.

- Add Heming Zhao as an ocfs2 reviewer.

- Fix mmap_prepare() state being copied onto a merged VMA rather than only
  onto a newly allocated VMA.

Linus, please merge this batch of MM hotfixes, thanks.


(yes, "MM".  nonmm material now has separate hotfixes branches so I'll
ask for nonmm changes to be pulled separately)

(ok, there's an ocfs2 patch here - that's transitional)


The following changes since commit 7891fbb9512f127826e1d5dbf380ee212bd15eb0:

  mm/folio: EXPORT_SYMBOL_FOR_KVM(lru_cache_drain_for_folio) (2026-09-08 23:28:06 -0700)

  MAINTAINERS: update Xu Xin's email (2026-09-18 08:20:15 -0700)

----------------------------------------------------------------
14 hotfixes.  10 are cc:stable.  11 are for MM.

Five are DAMON fixes.  One fixes an arm64 contpte bug where DAMON can
write past the end of a page-table page, resulting in memory corruption
and possible crashes.

Two are hugetlb fixes.  One fixes an mremap() address calculation bug
which can panic x86-64.

There's also a missing anon_vma publication barrier which can result in
hung tasks, and a writeback fix to keep long cgroup writeback drains from
delaying Tasks-RCU grace periods.

The remainder are smaller fixes and maintenance changes.
