SUNRPC: Respond promptly to server TCP resets
If the server sends us an RST error while we're in the TCP_ESTABLISHED state, then that will not result in a state change, and so the RPC client ends up hanging forever (see http://bugzilla.kernel.org/show_bug.cgi?id=11154) We can intercept the reset by setting up an sk->sk_error_report callback, which will then allow us to initiate a proper shutdown and retry... We also make sure that if the send request receives an ECONNRESET, then we shutdown too... Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
