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

2024-09-16T06:54:30+00:00

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"

fs: drop GFP_NOFAIL mode from alloc_page_buffers

2024-08-30T12:54:03+00:00

There is only one called of alloc_page_buffers and it doesn't require
__GFP_NOFAIL so drop this allocation mode.

2024-08-30T06:22:40+00:00

list_head can be initialized automatically with LIST_HEAD()
instead of calling INIT_LIST_HEAD().

buffer: Convert __block_write_begin() to take a folio

2024-08-07T09:33:36+00:00

Almost all callers have a folio now, so change __block_write_begin()
to take a folio and remove a call to compound_head().

fs: Convert aops->write_begin to take a folio

2024-08-07T09:33:21+00:00

Convert all callers from working on a page to working on one page
of a folio (support for working on an entire folio can come later).
Removes a lot of folio->page->folio conversions.

fs: Convert aops->write_end to take a folio

2024-08-07T09:32:02+00:00

Most callers have a folio, and most implementations operate on a folio,
so remove the conversion from folio->page->folio to fit through this
interface.

All callers now have a folio, so pass it in instead of converting
from a folio to a page and back to a folio again.  Saves a call
to compound_head().
