Yep, I was planning on sending an update to the MAINTAINERS with that
and some other updates soon.

In future revisions, I will put a link to the tree I developed
against. In the meantime, we send pull-requests from here:

https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git/log/?h=kunit

And that is what I used as my development base for this series.
