In addition to what Miguel said, I think it would also be useful to
mention that kselftests are expected to be run (e.g. via the above
command) on a system that is _running_ the kernel to be tested.

I think its worth pointing that out since in that sense they are different
from the other tests on this page, for which the example command can be run
from the kernel tree on an arbitrary system. Of course that's all written
in the docs you linked, but I assume spelling it out here will avoid
confusion.

Apart from that it looks good to me.
