I see.

Sorry, it sounds like I came across too strong there - it was just a little worrying to see failing or problematic tests disabled or otherwise artificially restricted.

I'm actually very excited to see you setting up ongoing, public testing using xfstests, I think it'll be a great benefit, especially if there's a way to see a particular test's results across several kernel versions and/or filesystems and/or architectures, so that patterns of failure can emerge.

If you find that xfstests is missing some feature or behavior which would facilitate testing in the automated environment, please do let us know what you need - or send patches.  :)

Thanks,
-Eric
