Ah, I did not realize we had a precedent for in-tree kernel test modules.

I don't think my proposal was significantly better than this
precedent, so I'll just adjust my patch to conform to it:
- move rbtree_test.c to lib/
- modify just lib/Makefile and lib/Kconfig.debug to get the module built.

Will send a replacement patch for this (so you can drop that one patch
from the stack and replace it with)

Thanks,
