Why do we start caring about out of tree code now? We never have,
really. If there is no interest in merging this stuff upstream,
then it's always the case that _their code_ needs to adapt iff you
want to run on a more recent kernel; the kernel dictates the uapi,
not some out of tree module. ;)

Cheers,
Daniel
