[PATCH OLK-6.6 v4 00/41] Support xfs atomic write of COW
by Long Li 08 Nov '25

08 Nov '25

The software solution supports XFS atomic write, but the hardware solution does not fully support it. v3->v4: 1. Fix issues of atomic write for aio. 2. Fix convert too much count fsb to writen for cow fork in xfs_atomic_write_cow_iomap_begin. Christoph Hellwig (1): xfs: cleanup xfs_vn_getattr Darrick J. Wong (7): xfs: add helpers to compute log item overhead xfs: add helpers to compute transaction reservation for finishing intent items xfs: separate out setting buftarg atomic writes limits xfs: ignore HW which cannot atomic write a single block xfs: allow sysadmins to specify a maximum atomic write limit at mount time xfs: fix delalloc write failures in software-provided atomic writes xfs: fix various problems in xfs_atomic_write_cow_iomap_begin John Garry (31): block: Pass blk_queue_get_max_sectors() a request pointer block: Generalize chunk_sectors support as boundary support block: Add core atomic write support block: Call blkdev_dio_unaligned() from blkdev_direct_IO() block: Add fops atomic write support block/fs: Pass an iocb to generic_atomic_write_valid() fs/block: Check for IOCB_DIRECT in generic_atomic_write_valid() block: Add bdev atomic write limits helpers fs: Export generic_atomic_write_valid() fs: iomap: Atomic write support xfs: Support atomic write for statx xfs: Validate atomic writes xfs: Support setting FMODE_CAN_ATOMIC_WRITE iomap: Minor code simplification in iomap_dio_bio_iter() iomap: Rename IOMAP_ATOMIC -> IOMAP_ATOMIC_HW iomap: Support SW-based atomic writes iomap: inline iomap_dio_bio_opflags() iomap: comment on atomic write checks in iomap_dio_bio_iter() iomap: rework IOMAP atomic flags fs: add atomic write unit max opt to statx xfs: rename xfs_inode_can_atomicwrite() -> xfs_inode_can_hw_atomic_write() xfs: allow block allocator to take an alignment hint xfs: refactor xfs_reflink_end_cow_extent() xfs: refine atomic write size check in xfs_file_write_iter() xfs: add xfs_atomic_write_cow_iomap_begin() xfs: add large atomic writes checks in xfs_direct_write_iomap_begin() xfs: commit CoW-based atomic writes atomically xfs: add xfs_file_dio_write_atomic() xfs: add xfs_calc_atomic_write_unit_max() xfs: update atomic write limits xfs: disallow atomic writes on DAX Prasad Singamsetty (2): fs: Initial atomic write support fs: Add initial atomic write support info to statx Documentation/ABI/stable/sysfs-block | 53 +++++ block/blk-core.c | 22 ++ block/blk-merge.c | 67 +++++- block/blk-mq.c | 2 +- block/blk-settings.c | 88 ++++++++ block/blk-sysfs.c | 33 +++ block/blk.h | 9 +- block/fops.c | 51 +++-- drivers/md/dm.c | 2 +- fs/aio.c | 8 +- fs/btrfs/ioctl.c | 2 +- fs/iomap/direct-io.c | 144 +++++++------ fs/iomap/trace.h | 3 +- fs/read_write.c | 22 +- fs/stat.c | 35 ++++ fs/xfs/libxfs/xfs_bmap.c | 5 + fs/xfs/libxfs/xfs_bmap.h | 6 +- fs/xfs/libxfs/xfs_log_rlimit.c | 3 + fs/xfs/libxfs/xfs_trans_resv.c | 291 +++++++++++++++++++++++++-- fs/xfs/libxfs/xfs_trans_resv.h | 21 ++ fs/xfs/xfs_bmap_item.c | 10 + fs/xfs/xfs_bmap_item.h | 3 + fs/xfs/xfs_buf.c | 37 +++- fs/xfs/xfs_buf.h | 6 +- fs/xfs/xfs_buf_item.c | 19 ++ fs/xfs/xfs_buf_item.h | 3 + fs/xfs/xfs_extfree_item.c | 10 + fs/xfs/xfs_extfree_item.h | 3 + fs/xfs/xfs_file.c | 87 +++++++- fs/xfs/xfs_inode.h | 22 ++ fs/xfs/xfs_iomap.c | 251 ++++++++++++++++++++++- fs/xfs/xfs_iomap.h | 1 + fs/xfs/xfs_iops.c | 102 +++++++++- fs/xfs/xfs_iops.h | 3 + fs/xfs/xfs_log_cil.c | 4 +- fs/xfs/xfs_log_priv.h | 13 ++ fs/xfs/xfs_mount.c | 126 ++++++++++++ fs/xfs/xfs_mount.h | 17 ++ fs/xfs/xfs_refcount_item.c | 10 + fs/xfs/xfs_refcount_item.h | 3 + fs/xfs/xfs_reflink.c | 146 +++++++++++--- fs/xfs/xfs_reflink.h | 5 + fs/xfs/xfs_rmap_item.c | 10 + fs/xfs/xfs_rmap_item.h | 3 + fs/xfs/xfs_super.c | 64 +++++- fs/xfs/xfs_trace.h | 108 ++++++++++ include/linux/blk_types.h | 8 +- include/linux/blkdev.h | 84 +++++++- include/linux/fs.h | 19 +- include/linux/iomap.h | 5 + include/linux/stat.h | 4 + include/uapi/linux/fs.h | 5 +- include/uapi/linux/stat.h | 13 +- io_uring/rw.c | 8 +- 54 files changed, 1894 insertions(+), 185 deletions(-) -- 2.39.2
