This patch does a new thing: adds a kernel self-test module into lib/tests/ and sets up the infrastructure to add new kernel self-test modules in that directory.
I don't see a problem with this per-se, but it is a new thing which we should think about.
In previous such cases (eg, kernel/rcutorture.c) we put those modules into the same directory as the code which is being tested. So to follow that pattern, this new code would have gone into lib/.
If we adopt your new proposal then we should perhaps also move tests such as rcutorture over into tests/. And that makes one wonder whether we should have a standalone directory for kernel selftest modules. eg tests/self-test-nmodules/.
