3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Trond Myklebust <[email protected]> commit 05e9cfb408b24debb3a85fd98edbfd09dd148881 upstream. We can currently loop forever in nfs4_lookup_root() and in nfs41_proc_secinfo_no_name(), if the first iteration returns a NFS4ERR_DELAY or something else that causes exception.retry to get set.
