From: Shida Zhang <[email protected]> Hi all, While investigating another problem [mentioned in v1], we identified some buggy code in the bio chain handling logic. This series addresses those issues and performs related code cleanup. Patches 1-4 fix incorrect usage of bio_chain_endio(). Patches 5-12 clean up repetitive code patterns in bio chain handling. v2: - Added fix for bcache. - Added BUG_ON() in bio_chain_endio(). - Enhanced commit messages for each patch v1: https://lore.kernel.org/all/[email protected]/ Shida Zhang (12): block: fix incorrect logic in bio_chain_endio block: prevent race condition on bi_status in __bio_chain_endio md: bcache: fix improper use of bi_end_io block: prohibit calls to bio_chain_endio block: export bio_chain_and_submit gfs2: Replace the repetitive bio chaining code patterns xfs: Replace the repetitive bio chaining code patterns block: Replace the repetitive bio chaining code patterns fs/ntfs3: Replace the repetitive bio chaining code patterns zram: Replace the repetitive bio chaining code patterns nvdimm: Replace the repetitive bio chaining code patterns nvmet: use bio_chain_and_submit to simplify bio chaining block/bio.c | 15 ++++++++++++--- drivers/block/zram/zram_drv.c | 3 +-- drivers/md/bcache/request.c | 6 +++--- drivers/nvdimm/nd_virtio.c | 3 +-- drivers/nvme/target/io-cmd-bdev.c | 3 +-- fs/gfs2/lops.c | 3 +-- fs/ntfs3/fsntfs.c | 12 ++---------- fs/squashfs/block.c | 3 +-- fs/xfs/xfs_bio_io.c | 3 +-- fs/xfs/xfs_buf.c | 3 +-- fs/xfs/xfs_log.c | 3 +-- 11 files changed, 25 insertions(+), 32 deletions(-) -- 2.34.1
