After further review I am going going have to disagree with you on this. Since all the context is cached on the initial mount the kernel should be using the call_usermodehelper() to call up to rpc.gssd to get the context, which means we could put this upcall noise to bed... forever! :-) I realize this is not going happen overnight, so I would still like to propose my nfs4_secure_mounts bool patch as bridge to the new call_usermodehelper() since its the cleanest solution so far...
