Same question as last time: have you tested this with multipage folios enabled? If you haven't tested XFS, then I'm guessing the answer is no, and you haven't fixed the bug I pointed out in the write_cache_pages() implementation.... -Dave.

I don't seem to have gotten your earlier comments, and I can't seem to find them on the mailing lists. Could you please send them again so I can take a look?

They are in the lore -fsdevel archive - no idea why you couldn't find them.... https://lore.kernel.org/linux-fsdevel/20221018210152.GH2703033@dread.disaster.area/ https://lore.kernel.org/linux-fsdevel/20221018214544.GI2703033@dread.disaster.area/ -Dave.
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 a lot 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. --- v4: Fixed a bug with reference counting in cifs changes - Reported-by: kernel test robot <oliver.sang@intel.com> Improved commit messages to be more meaningful Got some Acked-bys and Reviewed-bys v3: Rebased onto upstream 6.1 Simplified the ceph patch to only necessary changes Changed commit messages throughout to be clearer Got an Acked-by for another nilfs patch Got Tested-by for afs 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 | 58 ++++++++++---------- fs/cifs/file.c | 32 +++++++++-- 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 | 84 ++++++++++++++--------------- mm/page-writeback.c | 44 ++++++++-------- mm/swap.c | 10 ---- 19 files changed, 465 insertions(+), 418 deletions(-)
