Yes, you are right:
lock_sock(sk);
sk->sk_shutdown |= mode;
sk->sk_state_change(sk);
release_sock(sk);
if (sk->sk_type == SOCK_STREAM) {
sock_reset_flag(sk, SOCK_DONE);
vsock_send_shutdown(sk, mode);
Although sk_shutdown is ORed correctly, vsock_send_shutdown() is called with
just the shutdown() argument.
