It also looks like all your test code lives outside of the kernel
source dir. I take it you intend for tests to live in
tools/testing/selftests/ktf/ ?

Good point,
with this RFC it would be just to add another directory under ktf/
but this was just to find a simple way to integrate it below selftests,
without interfering with the current structure. 

I imagine a tighter integration/unification between normal Kbuild targets and selftests 
targets that also took kernel module building into consideration would be a better solution.

I think this is a good topic for discussion.
As I indicate above, I think it is problematic that test code has to be explicitly 
configured in as we configure code features of the kernel, which changes the "logical" 
kernel we build.

So some more "native" support for test modules are desired, IMHO.
