Isn't it designed to use "run_check" to break the test case if it returns any thing other than 0? IMHO any stderr output should be unexpected in this case.

The whole fstests is built upon the golden image matching mechanism, it's designed to let you don't have to check the return value of commands. IMO, this run_check should not be introduced in the first place. I agree that this "golden image matching" has some problems, e.g. we have to write lots of filters to make the outputs deterministic, it has both up and down sides, as well as the "check return value" way. But that's the way fstests has chosen to go since the beginning. > > IMHO any stderr output should be unexpected in this case. Yes, so any unexpected output breaks & fails the test, and we can see why it fails from the diff output. And run_check "hides" this info and makes it harder to parse the result, e.g. -setfattr: SCRATCH_MNT/snapshot/child: Operation not supported +failed: '/usr/local/bin/btrfs filesystem sync /mnt/testarea/scratch' +(see /root/workspace/xfstests/results//btrfs/btrfs/047.full for details) And without run_check: -setfattr: SCRATCH_MNT/snapshot/child: Operation not supported +ERROR: sync ioctl failed on '/mnt/testarea/scratch': No such file or directory We know why and where it fails.
