From 49f696914100780f6bf8e652d3468de0015d6172 Mon Sep 17 00:00:00 2001 From: Andy Grover Date: Thu, 9 Apr 2009 14:09:41 +0000 Subject: [PATCH] RDS: Establish connection before parsing CMSGs The first message to a remote node should prompt a new connection. Even an RDMA op via CMSG. Therefore move CMSG parsing to after connection establishment. Signed-off-by: Andy Grover Signed-off-by: David S.
