This patch set finishes the conversion by first converting all remaining filesystems to call folio_create_empty_buffers(), then renaming it back to create_empty_buffers(). I took the opportunity to make a few simplifications like making folio_create_empty_buffers() return the head buffer and extracting get_nth_bh() from nilfs2. A few of the patches in this series aren't directly related to create_empty_buffers(), but I saw them while I was working on this and thought they'd be easy enough to add to this series. Compile-tested only, other than ext4. v2: - Added the patch to fix the return type from grow_dev_page() - Fixed typo in subject line noticed by Andreas - Fixed missed assignment to 'bh' spotted by Andreas - Exported folio_copy() spotted by Ryusuke - Added various Reviewed-by tags from Pankaj, Ryusuke & Andreas Matthew Wilcox (Oracle) (27): buffer: Return bool from grow_dev_folio() buffer: Make folio_create_empty_buffers() return a buffer_head mpage: Convert map_buffer_to_folio() to folio_create_empty_buffers() ext4: Convert to folio_create_empty_buffers buffer: Add get_nth_bh() gfs2: Convert inode unstuffing to use a folio gfs2: Convert gfs2_getbuf() to folios gfs2: Convert gfs2_getjdatabuf to use a folio gfs2: Convert gfs2_write_buf_to_page() to use a folio nilfs2: Convert nilfs_mdt_freeze_buffer to use a folio nilfs2: Convert nilfs_grab_buffer() to use a folio nilfs2: Convert nilfs_copy_page() to nilfs_copy_folio() nilfs2: Convert nilfs_mdt_forget_block() to use a folio nilfs2: Convert nilfs_mdt_get_frozen_buffer to use a folio nilfs2: Remove nilfs_page_get_nth_block nilfs2: Convert nilfs_lookup_dirty_data_buffers to use folio_create_empty_buffers ntfs: Convert ntfs_read_block() to use a folio ntfs: Convert ntfs_writepage to use a folio ntfs: Convert ntfs_prepare_pages_for_non_resident_write() to folios ntfs3: Convert ntfs_zero_range() to use a folio ocfs2: Convert ocfs2_map_page_blocks to use a folio reiserfs: Convert writepage to use a folio ufs: Add ufs_get_locked_folio and ufs_put_locked_folio ufs: Use ufs_get_locked_folio() in ufs_alloc_lastblock() ufs; Convert ufs_change_blocknr() to use folios ufs: Remove ufs_get_locked_page() buffer: Remove folio_create_empty_buffers() fs/buffer.c | 68 +++++----- fs/ext4/inode.c | 14 +- fs/ext4/move_extent.c | 11 +- fs/gfs2/aops.c | 2 +- fs/gfs2/bmap.c | 48 ++++--- fs/gfs2/meta_io.c | 61 ++++----- fs/gfs2/quota.c | 37 +++--- fs/mpage.c | 3 +- fs/nilfs2/mdt.c | 66 +++++----- fs/nilfs2/page.c | 76 +++++------ fs/nilfs2/page.h | 11 -- fs/nilfs2/segment.c | 7 +- fs/ntfs/aops.c | 255 +++++++++++++++++------------------- fs/ntfs/file.c | 89 ++++++------- fs/ntfs3/file.c | 31 ++--- fs/ocfs2/aops.c | 19 +-- fs/reiserfs/inode.c | 80 +++++------ fs/ufs/balloc.c | 20 ++- fs/ufs/inode.c | 25 ++-- fs/ufs/util.c | 34 +++-- fs/ufs/util.h | 10 +- include/linux/buffer_head.h | 28 +++- mm/util.c | 1 + 23 files changed, 481 insertions(+), 515 deletions(-) -- 2.40.1
