    Subject[RFC PATCH v3 7/9] virtio/vsock: check SO_RCVLOWAT before wake up reader
    Date
    This adds extra condition to wake up data reader: do it only when number
    of readable bytes >= SO_RCVLOWAT. Otherwise, there is no sense to kick
    user,because it will wait until SO_RCVLOWAT bytes will be dequeued.
