OK so, we can just skip tainting considerations for selftests which
don't use modules for now. There may be selftests which do wonky
things in userspace but indeed I agree the userspace taint would
be better for those but I don't think it may be worth bother
worrying about those at this point in time.
But my point in that sharing a taint between kunit / selftests modules
does make sense and is easily possible. The unfortunate aspect is just
that selftests don't have a centralized runner, because I can just
run tools/testing/selftests/sysctl/sysctl.sh for example and that's it.
So I think we have no other option but to just add the module info
manually for selftests at this time.
