Pull more iomap updates from Darrick Wong: "In the past 10 days or so I've not heard any ZOMG STOP style complaints about removing ->writepage support from gfs2 or zonefs, so here's the pull request removing them (and the underlying fs iomap support) from the kernel: - Remove iomap_writepage and all callers, since the mm apparently never called the zonefs or gfs2 writepage functions" * tag 'iomap-6.0-merge-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: iomap: remove iomap_writepage zonefs: remove ->writepage gfs2: remove ->writepage gfs2: stop using generic_writepages in gfs2_ail1_start_one

mm/migrate: Add filemap_migrate_folio()

2022-08-02T16:34:04+00:00

There is nothing iomap-specific about iomap_migratepage(), and it fits a pattern used by several other filesystems, so move it to mm/migrate.c, convert it to be filemap_migrate_folio() and convert the iomap filesystems to use it.

gfs2: remove ->writepage

2022-07-22T17:59:16+00:00

->writepage is only used for single page writeback from memory reclaim, and not called at all for cgroup writeback. Follow the lead of XFS and remove ->writepage and rely entirely on ->writepages.

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. Signed-off-by: Matthew Wilcox (Oracle) Reviewed-by: Jeff Layton

gfs2: Convert to release_folio

Use a folio throughout gfs2_release_folio(). Signed-off-by: Matthew Wilcox (Oracle) Reviewed-by: Bob Peterson Reviewed-by: Jeff Layton

iomap: Convert to release_folio

2022-05-10T03:12:32+00:00

Change all the filesystems which used iomap_releasepage to use the new function. Signed-off-by: Matthew Wilcox (Oracle) Reviewed-by: Jeff Layton

fs: Change the type of filler_t

2022-05-09T20:36:48+00:00

By making filler_t the same as read_folio, we can use the same function for both in gfs2. We can push the use of folios down one more level in jffs2 and nfs. We also increase type safety for future users of the various read_cache_page() family of functions by forcing the parameter to be a pointer to struct file (or NULL).

fs: Convert mpage_readpage to mpage_read_folio

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

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(). Signed-off-by: Matthew Wilcox (Oracle)

fs: Convert iomap_readpage to iomap_read_folio

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

A straightforward conversion as iomap_readpage already worked in folios. Signed-off-by: Matthew Wilcox (Oracle)

fs: Convert __set_page_dirty_buffers to block_dirty_folio

2022-03-16T17:37:04+00:00

Convert all callers; mostly this is just changing the aops to point at it, but a few implementations need a little more work. Signed-off-by: Matthew Wilcox (Oracle) Tested-by: Damien Le Moal Acked-by: Damien Le Moal Tested-by: Mike Marshall # orangefs Tested-by: David Howells # afs
