Enable shutdown tests on overlayfs. This requires configuring overlayfs with TEST|SCRATCH_DEV pointing to block device, which act as base fs of overlay. The legacy config (pointing TEST|SCRATCH_DEV to existing directories) won't support shutdown. Extend _require_scratch_shutdown() to deal with overlay by checking shutdown support on $OVL_BASE_SCRATCH_MNT instead of $SCRATCH_MNT, so we check shutdown support status against the underlying upper fs of overlay. Introduce new _scratch_shutdown() helper to do the actual shutdown work and shutdown upper fs in the case of overlay. Also converting existing bare 'src/godown' calls to use this helper to avoid false failures when testing overlayfs. generic/042 and generic/050 assume $SCRATCH_DEV to be a local device, so add _require_local_device $SCRATCH_DEV rule.

# FS QA Test No. 388

# Test XFS log recovery ordering on v5 superblock filesystems. XFS had a problem
|
|
# where it would incorrectly replay older modifications from the log over more
|
|
# recent versions of metadata due to failure to update metadata LSNs during log
|
|
# recovery. This could result in false positive reports of corruption during log
|
|
# recovery and permanent mount failure.
|
|
#
|
|
# To test this situation, run frequent shutdowns immediately after log recovery.
|
|
# Ensure that log recovery does not recover stale modifications and cause
|
|
# spurious corruption reports and/or mount failures.
