These are the tests we were using to verify that filesystems are not tearing multi fs block atomic writes. Infact some of the tests like generic/772 actually helped us catch and fix issues in ext4's early implementations of multi fs block atomic writes and hence we feel these tests are useful to have in xfstests. We have tested these with scsi debug as well as a real nvme device supporting multi fs block atomic writes. Thoughts and suggestions are welcome!
