I think it will not be a issue bug wise, because it ends up getting cast to the proper struct in the end and the proper size to copy is detected. What actually gets passed that function above is not a struct sockaddr_storage. It is a sockaddr_in or socaddr_in6. It depends on if it is ipv6 or not. If you are just saying it would be nicer to be consistent in the struct used then it is a larger change that I think should be done in another patch. It will affect other drivers.-- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
