From 940aab490215424a269f93d2eba2794fc8b3e269 Mon Sep 17 00:00:00 2001 From: Malahal Naineni Date: Tue, 20 Sep 2011 17:27:14 -0700 Subject: [PATCH] Check validity of cl_rpcclient in nfs_server_list_show As soon as the nfs_client gets created, its cl_rpcclient is set to ERR_PTR(-EINVAL). The rpc client structure is allocated later. Check if the client is ready before using the cl_rpcclient pointer.
