Can't you just create an ext4 branch that has the kselftest-next branch
in it, that you build upon. And push that after the kunit test is
merged?

In the past I've had to rely on other branches in next, and would just
hold two branches myself. One with everything not dependent on the other
developer's branch, and one with the work that was. At the merge
window, I would either merge the two or just send two pull requests
with the two branches.
