From 8079fb785e34de6dff34bd846b8b79c212861edf Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 29 Jul 2014 17:26:12 -0400 Subject: xprtrdma: Handle additional connection events Commit 38ca83a5 added RDMA_CM_EVENT_TIMEWAIT_EXIT. But that status is relevant only for consumers that re-use their QPs on new connections. xprtrdma creates a fresh QP on reconnection, so that event should be explicitly ignored. Squelch the alarming "unexpected CM event" message.
