SubjectRe: [RFC v1 4/6] init: main: add KUnit to kernel init
Sorry for the late reply. I sent this thinking I would check in over
vacation, and then didn't.

I want to make sure it is called after late_init is done (so that you

runs before init*fs is loaded so that there is a mechanism to run
tests without having to put a userland together.

Just this function? No strong opinion.

If by "before this patch" you mean other stuff in this patchset?
