False positive tests

[JiyangLiuG]

Hi guys,

i use Ace to generate workloads of sequence length 2.
During running all the test cases in xfstests, around 600 tests are failed and mostly false positive, like test cases try to move A to A/B.

For example:
QA output created by 256257
/scratch/A/bar: No such file or directory
Silence is golden
QA output created by 256333
mv: can't rename '/scratch/A': Invalid argument
Silence is golden
QA output created by 256343
mv: can't rename '/scratch/A': Invalid argument
Silence is golden
QA output created by 256302
mv: can't rename '/scratch/A': Invalid argument
Silence is golden
QA output created by 256346
mv: can't rename '/scratch/A': Invalid argument
Silence is golden

Is there a way to find out/remove these test cases before start testing?

BR,
Jiyang
