Many of the changes still need review. If anyone has time this week to look over any of the affected areas (pagecache, afs, ceph, ciph, ext4, f2fs, or gfs) feedback would be much appreciated. Also, Thanks to David for looking at btrfs and Ryusuke for looking at nilfs already.
This patch series replaces find_get_pages_range_tag() with filemap_get_folios_tag(). This also allows the removal of multiple calls to compound_head() throughout. It also makes a good chunk of the straightforward conversions to folios, and takes the opportunity to introduce a function that grabs a folio from the pagecache. F2fs and Ceph have quite alot of work to be done regarding folios, so for now those patches only have the changes necessary for the removal of find_get_pages_range_tag(), and only support folios of size 1 (which is all they use right now anyways). I've run xfstests on btrfs, ext4, f2fs, and nilfs2, but more testing may be beneficial. The page-writeback and filemap changes implicitly work. Testing and review of the other changes (afs, ceph, cifs, gfs2) would be appreciated. --- v2: Got Acked-By tags for nilfs and btrfs changes Fixed an error arising in f2fs - Reported-by: kernel test robot <lkp@intel.com> Vishal Moola (Oracle) (23): pagemap: Add filemap_grab_folio() filemap: Added filemap_get_folios_tag() filemap: Convert __filemap_fdatawait_range() to use filemap_get_folios_tag() page-writeback: Convert write_cache_pages() to use filemap_get_folios_tag() afs: Convert afs_writepages_region() to use filemap_get_folios_tag() btrfs: Convert btree_write_cache_pages() to use filemap_get_folio_tag() btrfs: Convert extent_write_cache_pages() to use filemap_get_folios_tag() ceph: Convert ceph_writepages_start() to use filemap_get_folios_tag() cifs: Convert wdata_alloc_and_fillpages() to use filemap_get_folios_tag() ext4: Convert mpage_prepare_extent_to_map() to use filemap_get_folios_tag() f2fs: Convert f2fs_fsync_node_pages() to use filemap_get_folios_tag() f2fs: Convert f2fs_flush_inline_data() to use filemap_get_folios_tag() f2fs: Convert f2fs_sync_node_pages() to use filemap_get_folios_tag() f2fs: Convert f2fs_write_cache_pages() to use filemap_get_folios_tag() f2fs: Convert last_fsync_dnode() to use filemap_get_folios_tag() f2fs: Convert f2fs_sync_meta_pages() to use filemap_get_folios_tag() gfs2: Convert gfs2_write_cache_jdata() to use filemap_get_folios_tag() nilfs2: Convert nilfs_lookup_dirty_data_buffers() to use filemap_get_folios_tag() nilfs2: Convert nilfs_lookup_dirty_node_buffers() to use filemap_get_folios_tag() nilfs2: Convert nilfs_btree_lookup_dirty_buffers() to use filemap_get_folios_tag() nilfs2: Convert nilfs_copy_dirty_pages() to use filemap_get_folios_tag() nilfs2: Convert nilfs_clear_dirty_pages() to use filemap_get_folios_tag() filemap: Remove find_get_pages_range_tag() fs/afs/write.c | 114 +++++++++++++++++---------------- fs/btrfs/extent_io.c | 57 +++++++++-------- fs/ceph/addr.c | 138 ++++++++++++++++++++-------------------- fs/cifs/file.c | 33 +++++++++- fs/ext4/inode.c | 55 ++++++++-------- fs/f2fs/checkpoint.c | 49 +++++++------- fs/f2fs/compress.c | 13 ++-- fs/f2fs/data.c | 69 ++++++++++---------- fs/f2fs/f2fs.h | 5 +- fs/f2fs/node.c | 72 +++++++++++---------- fs/gfs2/aops.c | 64 ++++++++++--------- fs/nilfs2/btree.c | 14 ++-- fs/nilfs2/page.c | 59 ++++++++--------- fs/nilfs2/segment.c | 44 +++++++------ include/linux/pagemap.h | 32 +++++++--- include/linux/pagevec.h | 8 --- mm/filemap.c | 87 ++++++++++++------------- mm/page-writeback.c | 44 +++++++------ mm/swap.c | 10 --- 19 files changed, 507 insertions(+), 460 deletions(-)
