This is exactly what is happening. Three or four responses are *not* being enqueued because there is not enough write space. The problem I'm seeing is those sockets are never getting re-enqueued. Your patch is depending on the tcp layer calling svc_write_space() [when the write space is freed] to start the enqueuing of the sockets. For some reason that is not happening in my case.....
