I am confused by the patch that originally caused this:

        if (sk->sk_family == AF_INET6)
                return ipv6_rcv_saddr_equal(&sk->sk_v6_rcv_saddr,
-                                           &sk2->sk_v6_rcv_saddr,
+                                           inet6_rcv_saddr(sk2),
                                            sk->sk_rcv_saddr,
                                            sk2->sk_rcv_saddr,

Shouldn't the first argument also be changed to use inet6_rcv_saddr()?
