I don't like it. Using defined(MODULE) in a header file seems quite
risky (although I see there are occurrences of this already.) But more
importantly, this means that you can have all pieces enabled in your
kernel but the code will be silently stubbed out because the
combinations of Y and M happens to be unsupported but this is nowhere
documented. This is wrong.
