Subject: [RFC PATCH mtd-utils 104/110] tests: ubifs_tools: fsck_tests: Add cycle_powercut+fsck test
Inject powercut while doing fsstress on mounted UBIFS, check the
consistency of UBIFS after fsck.
This testscase mainly makes sure that fsck.ubifs can make UBIFS
image be consistent in common stress cases and powercut cases.
