Merge tag 'vfs-6.12.folio' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs

Browse Source 
Pull vfs folio updates from Christian Brauner:
 "This contains work to port write_begin and write_end to rely on folios
  for various filesystems.

  This converts ocfs2, vboxfs, orangefs, jffs2, hostfs, fuse, f2fs,
  ecryptfs, ntfs3, nilfs2, reiserfs, minixfs, qnx6, sysv, ufs, and
  squashfs.

  After this series lands a bunch of the filesystems in this list do not
  mention struct page anymore"
