xfstests(./check) is done.

- v6.0-rc3+ (commit dcf8e5633e2)

- nbdublk/nbd is test device, virtio-scsi is scratch device

- both nbdublk and nbd survive, and result is same too:

Failures: generic/471 generic/633 generic/644 generic/645 xfs/019 xfs/049 xfs/082 xfs/144 xfs/191 xfs/199 xfs/543 xfs/544 xfs/545 xfs/549
Failed 14 of 1069 tests

Thanks,
