This means for a power failure or any hardware failure all or none of the data from the write will be stored, never a mix of old and new data. This work is already supported for block devices. If a block device is opened with O_DIRECT and the block device supports atomic write, then FMODE_CAN_ATOMIC_WRITE is added to the file of the opened block device. This contains the work to expand atomic write support to filesystems, specifically ext4 and XFS. Currently, only support for writing exactly one filesystem block atomically is added. Since it's now possible to have filesystem block size > page size for XFS, it's possible to write 4K+ blocks atomically on x86" * tag 'vfs-6.13.untorn.writes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: iomap: drop an obsolete comment in iomap_dio_bio_iter ext4: Do not fallback to buffered-io for DIO atomic write ext4: Support setting FMODE_CAN_ATOMIC_WRITE ext4: Check for atomic writes support in write iter ext4: Add statx support for atomic writes xfs: Support setting FMODE_CAN_ATOMIC_WRITE xfs: Validate atomic writes xfs: Support atomic write for statx fs: iomap: Atomic write support fs: Export generic_atomic_write_valid() block: Add bdev atomic write limits helpers fs/block: Check for IOCB_DIRECT in generic_atomic_write_valid() block/fs: Pass an iocb to generic_atomic_write_valid() |
