In-kernel socket users rely on this callback to detect when incoming connections are available. Currently the sk->sk_state_change() callback is invoked by vmci_transport.c. This happens to work for userspace applications since sk->sk_state_change = sock_def_wakeup() and sk->sk_data_ready = sock_def_readable() both wake up the accept() waiter. In-kernel socket users, on the other hand, fail to detect incoming connections. Signed-off-by: Stefan Hajnoczi Signed-off-by: David S.
