Matthew Wilcox (Oracle) ce3bb0d2cb cifs: Convert cifs to read_folio
This is a "weak" conversion which converts straight back to using pages.
CIFS should probably be converted to use netfs_read_folio() by someone
familiar with it.

Matthew Wilcox (Oracle) fb12489b0d btrfs: Convert btrfs to read_folio
This is a "weak" conversion which converts straight back to using pages.
A full conversion should be performed at some point, hopefully by
someone familiar with the filesystem.

Matthew Wilcox (Oracle) d7e0f539d8 afs: Convert afs_symlink_readpage to afs_symlink_read_folio
This function mostly used folios already, and only a few minor changes
were needed.

Matthew Wilcox (Oracle) a77f580a2d fs: Convert simple_readpage to simple_read_folio
This is a full folio conversion; it is prepared to handle folios of

Matthew Wilcox (Oracle) f132ab7d3a fs: Convert mpage_readpage to mpage_read_folio
mpage_readpage still works in terms of pages, and has not been audited
for correctness with large folios, so include an assertion that the
filesystem is not passing it large folios.  Convert all the filesystems
to call mpage_read_folio() instead of mpage_readpage().

Matthew Wilcox (Oracle) 2c69e20579 fs: Convert block_read_full_page() to block_read_full_folio()
This function is NOT converted to handle large folios, so include
an assert that the filesystem isn't passing one in.  Otherwise, use
the folio functions instead of the page functions, where they exist.
Convert all filesystems which use block_read_full_page().

Matthew Wilcox (Oracle) 5efe7448a1 fs: Introduce aops->read_folio
Change all the callers of ->readpage to call ->read_folio in preference,

by the end of the series.

Matthew Wilcox (Oracle) 6c2ae0d5db buffer: Rewrite nobh_truncate_page() to use folios
- Calculate iblock directly instead of using a while loop
 - Move has_buffers to the end to remove a backwards jump
 - Use __filemap_get_folio() instead of grab_cache_page(), which
   removes a spurious FGP_ACCESSED flag.
 - Eliminate length and pos variables
 - Use folio APIs where they exist

Miaohe Lin 65aa6b5a18 filemap: Remove obsolete comment in lock_page
We no longer need the page's inode pinned.  This comment dates back to
commit db37648cd6 ("[PATCH] mm: non syncing lock_page()") which added
lock_page_nosync().  That was removed by commit 7eaceaccab ("block:
remove per-queue plugging") which also made this comment obsolete.
