-Currently, the client will attempt to use krb5i in the SETCLIENTID call
-even if rpc.gssd isn't running. When that fails, it'll then fall back to
-RPC_AUTH_UNIX. This introduced a delay when mounting if rpc.gssd isn't
-running, and causes warning messages to pop up in the ring buffer.
-
-Check to see if rpc.gssd is running before even attempting to use krb5i
-auth, and just silently skip trying to do so if it isn't. In the event
-that the admin is actually trying to mount with krb5*, it will still
-fail at a later stage of the mount attempt.

-the dummy gssd pipe, users that run rpc.gssd see a lot of these messages

-Bugzilla: N/A
-Upstream-status: queued in NFS git tree (for 3.13/3.14?)
-
-Now that we have a more reliable method to tell if gssd is running, we
-can replace the sn->gssd_running flag with a function that will query to
-see if it's up and running.
-
-There's also no need to attempt an upcall that we know will fail, so
-just return -EACCES if gssd isn't running. Finally, fix the warn_gss()
-message not to claim that that the upcall timed out since we don't
-necesarily perform one now when gssd isn't running, and remove the
-extraneous newline from the message.
