So I pulled this, but then I almost immediately unpulled it.

My reason for doing that may be odd, but it's because of the top-level
'kunit' directory. This shouldn't be on the top level.

The reason I react so strongly is that it actually breaks my finger
memory. I don't type out filenames - I auto-compete them. So "kernel/"
is "k<tab>", "drivers/" is "d<tab>" etc.

It already doesn't work for everything ("mm/" is actually "mm<tab>"
not because we have files in the git tree, but because the build
creates various "module" files), but this breaks a common pattern for
me.

Can the kernel parts please move to lib/kunit/ or something like that?
