Chengguang Xu 2b4eae7fd8 common/rc: add scratch shutdown support for overlayfs
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 468
#
# This testcase is a fallocate variant of generic/392, it expands to test
# block preallocation functionality of fallocate.
# In this case, we are trying to execute:
# 1. fallocate {,-k}
# 2. f{data,}sync
# 3. power-cuts
# 4. recovery filesystem during mount
# 5. check inode's metadata
#
# In the case of fsync, filesystem should recover all the inode metadata, while
# recovering i_blocks and i_size at least for fdatasync, so this testcase excepts
# that inode metadata will be unchanged after recovery.
