From 517be09def6cd7bc231222ee756fde8ea245a6fe Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 6 Oct 2009 15:42:20 -0400 Subject: [PATCH] NFSv4: Fix the referral mount code Fix a typo which causes try_location() to use the wrong length argument when calling nfs_parse_server_name(). This again, causes the initialisation of the mount's sockaddr structure to fail. Also ensure that if nfs4_pathname_string() returns an error, then we pass that error back up the stack instead of ENOENT.
