The rest of the networking layer uses SOCK_ASYNC_NOSPACE to signal whether or not we have someone waiting for buffer memory. Convert the SUNRPC layer to use the same idiom. Remove the unlikely()s in xs_udp_write_space and xs_tcp_write_space. In fact, the most common case will be that there is nobody waiting for buffer space. SOCK_NOSPACE is there to tell the TCP layer whether or not the cwnd was limited by the application window. Ensure that we follow the same idiom as the rest of the networking layer here too. Finally, ensure that we clear SOCK_ASYNC_NOSPACE once we wake up, so that write_space() doesn't keep waking things up on xprt->pending. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> |
