Hmm...should we maybe apply this naming scheme to all the tests then?
I think Kees might have suggested this. I am actually not sure whether
or not we should and would like to get other people's input.

It is a valid point that test-test or example-test are too general of
names for modules, but if this is the case, I think that inode-test is
probably too general as well. But if we are going that far, maybe we
should rename everything *-kunit-test.c.
