If we are to test this for XFS then we need to ensure that HW atomics are
available.
Why is that? Now with the verification step happening after writes,
software atomic writes should also pass this test since there are no
racing writes to the verify reads.

Sure, but racing software atomic writes against other software atomic writes is not safe.

Thanks,
