Subject: [PATCH] VSOCK: call sk->sk_data_ready() on accept()
When a listen socket enqueues a connection for userspace to accept(),
the sk->sk_data_ready() callback should be invoked. 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.
