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
