From 280ebcf97ce4b252c72af74ff3149ab5a5c9e680 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 2 Sep 2013 13:28:04 -0400 Subject: [PATCH] SUNRPC: rpcauth_create needs to know about rpc_clnt clone status Ensure that we set rpc_clnt->cl_parent before calling rpc_client_register so that rpcauth_create can find any existing RPCSEC_GSS caches for this transport.
