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"

* tag 'vfs-6.12.folio' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs: (61 commits)
  Squashfs: Ensure all readahead pages have been used
  Squashfs: Rewrite and update squashfs_readahead_fragment() to not use page->index
  Squashfs: Update squashfs_readpage_block() to not use page->index
  Squashfs: Update squashfs_readahead() to not use page->index
  Squashfs: Update page_actor to not use page->index
  jffs2: Use a folio in jffs2_garbage_collect_dnode()
  jffs2: Convert jffs2_do_readpage_nolock to take a folio
  buffer: Convert __block_write_begin() to take a folio
  ocfs2: Convert ocfs2_write_zero_page to use a folio
  fs: Convert aops->write_begin to take a folio
  fs: Convert aops->write_end to take a folio
  vboxsf: Use a folio in vboxsf_write_end()
  orangefs: Convert orangefs_write_begin() to use a folio
  orangefs: Convert orangefs_write_end() to use a folio
  jffs2: Convert jffs2_write_begin() to use a folio
  jffs2: Convert jffs2_write_end() to use a folio
  hostfs: Convert hostfs_write_end() to use a folio
  fuse: Convert fuse_write_begin() to use a folio
