xfs/078 only forces crc=0 for block size <= 1024 bytes.  Would be
kinds sad to disable it just to work around this case.

xfs/096 requires an obsolete mkfs without input validation, but
I guess adding the doesn't hurt

xfs/300 needs the check, it doesn't run on my test setup because it
requires selinux.
