This test is only valid for CRC enabled XFS, and test fails with MKFS_OPTIONS="-m crc=0" being set (no mount failure detected). Fix it by adding _require_scratch_xfs_crc, which ensures scratch device has CRC support and enabled.

# FS QA Test No. 137
|
|
#
|
|
# XFS v5 supers carry an LSN in various on-disk structures to track when
|
|
# associated metadata was last written to disk. These metadata LSNs must always
|
|
# be behind the current LSN as dictated by the log to ensure log recovery
|
|
# correctness after a potential crash. This test uses xfs_db to intentionally
|
|
# put the current LSN behind metadata LSNs and verifies that the kernel and
|
|
# xfs_repair detect the problem.
