  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.
