From ea33e6c3e79d23ef693b7ed3171ef90dddfbfc15 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 5 Apr 2013 13:22:50 -0400 Subject: [PATCH] NFSv4: Fix issues in nfs4_discover_server_trunking - Ensure that we exit with ENOENT if the call to ops->get_clid_cred() fails. - Handle the case where ops->detect_trunking() exits with an unexpected error, and return EIO.
