Tests in shutdown group are supposed to test journal recovery after filesystem shutdown, and the tests assume the filesystem in test has journal support. But with the ext4 shutdown function added in 4.11-rc kernel, ext2 gains shutdown support too when driving with ext4 driver, so generic/051 fails because fs corruption after test. Adding _require_metadata_journaling to all generic tests in shutdown group to ensure there's journal present. generic/050 is skipped because it has _require_scratch_nocheck, which indicates no fsck is done after test.

# FS QA Test No. 042

# Test stale data exposure via writeback using various file allocation
|
|
# modification commands. The presumption is that such commands result in partial
|
|
# writeback and can convert a delayed allocation extent, that might be larger
|
|
# than the ranged affected by fallocate, to a normal extent. If the fs happens
|
|
# to crash sometime between when the extent modification is logged and writeback
|
|
# occurs for dirty pages within the extent but outside of the fallocated range,
|
|
# stale data exposure can occur.
