fs: Change try_to_free_buffers() to take a folio

2022-05-10T03:12:34+00:00

All but two of the callers already have a folio; pass a folio into
try_to_free_buffers().  This removes the last user of cancel_dirty_page()
so remove that wrapper function too.

mm,fs: Remove aops->readpage

2022-05-09T20:28:36+00:00

With all implementations of aops->readpage converted to aops->read_folio,
we can stop checking whether it's set and remove the member from aops.

fs: Convert block_read_full_page() to block_read_full_folio()

2022-05-09T20:21:44+00:00

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().

fs: Introduce aops->read_folio

2022-05-09T20:21:40+00:00

Change all the callers of ->readpage to call ->read_folio in preference,
if it exists.  This is a transitional duplication, and will be removed
by the end of the series.

buffer: Rewrite nobh_truncate_page() to use folios

2022-05-08T18:45:57+00:00

 - 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

fs: Convert is_dirty_writeback() to take a folio

2022-05-08T18:45:56+00:00

Pass a folio instead of a page to aops->is_dirty_writeback().
Convert both implementations and the caller.

buffer: Call aops write_begin() and write_end() directly

2022-05-08T18:28:19+00:00

pagecache_write_begin() and pagecache_write_end() are now trivial
wrappers, so call the aops directly.
