Hi Brad -

(cc: xfs list too)

The Ubuntu kernel team has been putting some automated testing
infrastructure in place. We are very interested in engaging with
the appropriate upstream developers. We have been running the
xfstests that come as part of the autotest testing framework.
Some of these tests fail or never complete when run against an
Ext4 file-system. 

Which ones?  Feel free to file bugs or send mail.  Tests should pass.
Sometimes it's a test bug, though, of course ;)

Our initial questions are:

1. Is this an appropriate set of tests to be run as regression
   tests?

Yes, that's what it's for!

2. Is there a list of the xfstests that are appropriate for
   Ext4?

Any test which says

_supported_fs generic
or
_supported_fs ext4

can run on ext4, and should in theory pass.  I think there are
about 100 of them by now.

There is a "dangerous" group (see groups file) which contains test nrs that
might stop testing via a hang or panic.  But don't skip those by
default; newer kernels with those bugs fixed _should_ pass them too.

3. Are there additional regression tests that would be beneficial
   to the Linux community for us to be running?

We've been encouraging new tests to be written for xfstests lately,
and it's gotten a good amount of traction.  There certainly may be
other things out there, though.
