Subject: xfs/045: can't change UUID on v5 filesystems.
X-Git-Tag: v2022.05.01~2886
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=da8f501cb3ccf2fef04837b74fa0f525e50f6d7e;p=xfstests-dev.git

xfs/045: can't change UUID on v5 filesystems.

So pass "-m crc=0" to the scratch_mkfs command so that we only run
on old v4 format filesystems where the UUID can be changed.
