xfs_io atomic write support is a dependency of the scsi and nvme atomic write
tests. The xfs_io atomic write support was introduced across different
versions so if xfs_io pwrite supports the -A (Atomic Write) option, it doesn't
necessarily support statx atomic write fields so that needs to be verified
separately.
