Yeah, of course, but that's actually the benefit of that method, the
stuff in there is compiled. You already have a static inline for that
(mesh_is_connected or something) though.

As it stands, your patch really makes the driver hard to maintain, one
will have to pretty much compile with and without mesh configured to
test changes. IMHO. YMMV, and I don't really think my opinion for that
driver should matter much :)
