Because there are some places have to interpret the structure, without this union, they need to cast to either sockaddr_in or sockaddr_in6 first, which is not as pretty as using a union. For example, the code in netpoll: ipv6_addr_equal(daddr, &np->local_ip.sin6.sin6_addr) without the union, it would be: struct sockaddr_in6 *addr = (struct sockaddr_in6 *) &np->local_ip; ipv6_addr_equal(daddr, addr->sin6_addr); Too bad ipv6_addr_equal() doesn't take a (void *). -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
