It's one of the rare warnings that I find totally useless in field, because it's simply against the principle of using function pointers with different functions having the same interface but different implementations. As your code evolves you end up with unused on absolutely *all* of the arguments of *all* such functions, which makes them a real pain to add and tends to encourage poor practices such as excessive code reuse just by laziness or boredom. BTW it's one of those that are already disabled in the kernel and we could very well do the same here. Willy
