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. 079
|
|
#
|
|
# Regression test for a bug in the log record checksum mechanism of XFS. Log
|
|
# records are checksummed during recovery and a warning or mount failure occurs
|
|
# on checksum verification failure. XFS had a bug where the checksum mechanism
|
|
# verified different parts of a record depending on the current log buffer size.
|
|
# This caused spurious checksum failures when a filesystem is recovered using a
|
|
# different log buffer size from when the filesystem crashed.
|
|
#
|
|
# Test that log recovery succeeds with a different log buffer size from when the
|
|
# filesystem crashed.
