Instead of setting bio->bi_end_io to end_bio_bh_io_sync() which then calls bh->b_end_io(), the new bh_submit() and __bh_submit() interfaces set bio->bi_end_io to the appropriate completion handler directly, replacing two indirect function calls in the completion path with one. It is also one fewer function pointer in the middle of a writable data structure that can be corrupted, it shrinks struct buffer_head from 104 to 96 bytes allowing roughly 7% more buffer_heads to be cached in the same amount of memory, and it removes some atomic operations as the buffer refcount is no longer incremented before calling the end_io handler. All in-tree users (fs/buffer.c itself, ext4, jbd2, ocfs2, gfs2, nilfs2, and md-bitmap) are converted, and submit_bh(), mark_buffer_async_write(), and end_buffer_write_sync() are removed" * tag 'vfs-7.2-rc1.bh' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (34 commits) buffer: Remove end_buffer_write_sync() buffer: Change calling convention for end_buffer_read_sync() buffer: Remove b_end_io buffer: Remove submit_bh() md-bitmap: Convert read_file_page and write_file_page to bh_submit() nilfs2: Convert nilfs_mdt_submit_block to bh_submit() nilfs2: Convert nilfs_gccache_submit_read_data to bh_submit() nilfs2: Convert nilfs_btnode_submit_block to bh_submit() buffer: Remove mark_buffer_async_write() gfs2: Convert gfs2_aspace_write_folio to bh_submit() gfs2: Remove use of b_end_io in gfs2_meta_read_endio() gfs2: Convert gfs2_dir_readahead to bh_submit() gfs2: Convert gfs2_metapath_ra to bh_submit() ocfs2: Convert ocfs2_write_super_or_backup to bh_submit() ocfs2: Convert ocfs2_read_blocks to bh_submit() ocfs2: Convert ocfs2_read_block to bh_submit() ocfs2: Convert ocfs2_write_block to bh_submit() jbd2: Convert jbd2_write_superblock() to bh_submit() jbd2: Convert journal commit to bh_submit() ext4: Convert ext4_commit_super() to bh_submit() ... |
