Hi Jorgen, virtio-vsock doesn't use vsock_pending_work() but I may have spotted a problem that affects the VMCI transport. I'm not sending a patch because I can't test it.
1. During vsock_accept() listener->sk_ack_backlog is decremented. 2. vsock_pending_work() will decrement listener->sk_ack_backlog again if vsk->rejected. The result is that sk_ack_backlog can be invalid. It only happens in the case where the listener socket has an error. Maybe in practice it's not a problem because the server application will close the listener socket if there is an error... Stefan
