X-Git-Tag: MMI-PSA29.97-13-9~28983^2^2~39 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=670f94573104b4a25525d3fcdcd6496c678df172;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git SUNRPC: Ensure we set XPRT_CLOSING only after we've sent a tcp FIN... ...so that we can distinguish between when we need to shutdown and when we don't. Also remove the call to xs_tcp_shutdown() from xs_tcp_connect(), since xprt_connect() makes the same test.
