One very minor nit below, other than that this looks great! I couldn't
have done a better job myself.

Minor nit: Elsewhere you use KUnit.

I wasn't going to say anything because so many people go with the
"Kunit" capitalization (and actually I kind of prefer it), but you
should at least be consistent within your patch.

Here is the other capitalization.
