I'm seeing generic/232 fail from time to time when running a 4.14-rc1 kernel on xfstest-bld's most recent kvm-xfstests test appliance. In one set of trials, it failed in the same manner 4 out of 10 times when running the 4k test configuration for ext4. The failure bisects to "quota: Do not acquire dqio_sem for dquot overwrites in v2 format" (ab2b86360f6e). When this patch was reverted in a 4.14-rc1 kernel, the failure did not reoccur in a series of 20 trials. Example output from the failed test: QA output created by 232 Testing fsstress seed = S Comparing user usage 218a219 > #3740 -- 4 0 0 1 0 0 245a247 > #45 -- 0 0 0 1 0 0 Note: I'm also seeing a similar failure for generic/233, but the patch containing the root cause likely comes somewhere after ab2b86360f6e. I'll post another bug report once I locate it. Thanks, Eric
