No harm, no foul. We really don't mind constructive criticism. We are also
eager to get this setup and running. We will try to contribute more than
just running tests.

I do want to point out that we are using the xfstests which is a snapshot
in autotest. We do also look at the latest xfstests in the official xfstests
repo and add it in when we see a delta. We will also work with the autotest
maintainers to stay more up-to-date with xfstests.

Thanks,
Brad
