Overlayfs introduces some complexity with regards to what path we have to use to shut down the scratch filesystem: it's SCRATCH_MNT for regular filesystems, but it's OVL_BASE_SCRATCH_MNT (i.e. the lower mount of the overlay) if overlayfs is enabled. The helper works through all that, so we might as well use it. Signed-off-by: Darrick J.

# 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.
