I have reproduced the problem running only test 232:
# Run fsstress with quotas enabled and verify accounted quotas in the end


There is very little to this test (other than running fsstress).
It's basically:
   quotacheck -u -g $SCRATCH_MNT 2>/dev/null
   quotaon -u -g $SCRATCH_MNT 2>/dev/null
   _check_quota_usage
   _fsstress

Now I'll look a little closer at the XFS path, and will try to
grab some extra information while reproducing it.
