Sorry, yes, kind of?  I pasted that in for brevity, but it's basically
that for example all of test/py/tests/test_fs/test_unlink.py fails if
you fsck the image in question after each test.  If you apply
https://patchwork.ozlabs.org/patch/1041186/ (to avoid spurious ext4
failures) and then https://patchwork.ozlabs.org/patch/1041181/ and run
'make tests' you'll see the full output.
