You have an exit code. Further, it's not in the .out > file, so you can see just by looking at that that there's no output expected. Yes, it's not a must-have from the test's point of view. But it's kind of xfstests' convention. xfstests takes it as a clear indication that this test expects no output, so anyone who's familiar with xfstests knows the test has no output and isn't surprised. Without this message people just get confused and wonder what's the expected result. As Amir pointed out, not all tests with empty output print this message (mostly some really old tests), but most of such tests do print. > > Actually, how do I *prevent* the output comparator from comparing?

You could dump & append any debug message to $seqres.full file, it's for debug purpose and it defaults to <xfstests>/result/generic/421.full e.g. echo "a=$a_supported d=$d_supported c=$c_supported i=$i_supported" >>$seqres.full Thanks, Eryu -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
