+static struct sock *hvsock_create(struct net *net, struct socket *sock,
+				  gfp_t priority, unsigned short type)
+{
+	struct hvsock_sock *hvsk;
+	struct sock *sk;
+
+	sk = sk_alloc(net, AF_HYPERV, priority, &hvsock_proto, 0);
+	if (!sk)
+		return NULL;

 ...

+	/* Looks stream-based socket doesn't need this. */
+	sk->sk_backlog_rcv = NULL;
+
+	sk->sk_state = 0;
+	sock_reset_flag(sk, SOCK_DONE);

All of these are unnecessary initializations, since sk_alloc() zeroes
out the 'sk' object for you.
