From: Zhihao Cheng Date: Mon, 11 Nov 2024 09:08:23 +0000 (+0800) Subject: tests: ubifs_tools: fsck_tests: Add cycle_powercut+fsck test X-Git-Tag: v2.3.0~25 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=e06aa684857345f8be397a481cf726a1051734d7;p=mtd-utils.git 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.
