Pull buffer_head updates from Christian Brauner: "This removes b_end_io from struct buffer_head. 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() ...

buffer: Change calling convention for end_buffer_read_sync()

2026-06-04T08:28:10+00:00

Unify end_buffer_read_sync() and __end_buffer_read_notouch() by requiring the caller put the refcount on the buffer. The only caller is in the gfs2_meta_read() path, and there we can put the refcount after locking the buffer.

gfs2: page poisoning fix

2026-05-29T09:11:40+00:00

Processes can write to the last page of a file using mmap, and when the file size is not a multiple of the page size, this can be used to write beyond the end of the file. This is sometimes referred to as page poisoning, and it is not a problem in itself because the data beyond eof will be ignored. However, we currently fail to clear out any space beyond the end of the file that we skip over when the file size is increased, so that "poison" can end up getting exposed. Fix that. Fixes xfstest generic/363. Signed-off-by: Andreas Gruenbacher
