Previously _scratch_mount didn't check the mount status and most tests continue to run even if the mount failed (unless test checks for the mount status explicitly). This would result in running tests on the underlying filesystem (usually rootfs) and implicit test failures, and such failures can be annoying and are usually hard to debug. Now _fail test by default if _scratch_mount failed and introduce _try_scratch_mount for tests that need to check mount results themselves.

# 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.
