From fba91afbec2c004e2c8733ae9e0ca6998e962c64 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 11 Mar 2009 14:06:41 -0400 Subject: SUNRPC: Fix an Oops due to socket not set up yet... We can Oops in both xs_udp_send_request() and xs_tcp_send_request() if the call to xs_sendpages() returns an error due to the socket not yet being set up. Deal with that situation by returning a new error: ENOTSOCK, so that we know to avoid dereferencing transport->sock.
