Arseniy Krasnov 94e5f64283 virtio/vsock: send credit update during setting SO_RCVLOWAT ... [ Upstream commit 0fe1798968 ] Send credit update message when SO_RCVLOWAT is updated and it is bigger than number of bytes in rx queue. It is needed, because 'poll()' will wait until number of bytes in rx queue will be not smaller than O_RCVLOWAT, so kick sender to send more data. Otherwise mutual hungup for tx/rx is possible: sender waits for free space and receiver is waiting data in 'poll()'. Rename 'set_rcvlowat' callback to 'notify_set_rcvlowat' and set 'sk->sk_rcvlowat' only in one place (i.e. 'vsock_set_rcvlowat'), so the transport doesn't need to do it.
