It's so easy to get lost and hard to maintain. How about make _scratch_mkfs_xfs do the work automatically if it finds the newly created fs is a v4 xfs? And I went through all tests that have explicit "-m crc=0" mkfs option, and I found that there're some other tests need fix too. xfs/045, it doesn't fail, but the test expects a mount failure anyway, just that it's caused by quota options now. xfs/132, it fails to mount xfs and needs the fix. But it still fails even after the fix, but that's a different issue. xfs/300, the test itself passes, it just causes subsequent _scratch_mount to fail in _check_xfs_filesystem(). I think we could just umount $SCRATCH_DEV explicitly after test, so _check_xfs_filesystem() won't try to mount it again.
