commit c929ea0b910355e1876c64431f3d5802f95b3d75 upstream.

After removing sunrpc module, I get many kmemleak information as,
unreferenced object 0xffff88003316b1e0 (size 544):
  comm "gssproxy", pid 2148, jiffies 4294794465 (age 4200.081s)

I found, the ida information (dynamic memory) isn't cleanup.

<title>SUNRPC: Add a framework to clean up management of rpc_pipefs directories</title>

The current system requires everyone to set up notifiers, manage directory
locking, etc.
What we really want to do is have the rpc_client create its directory,
and then create all the entries.

This patch will allow the RPCSEC_GSS and NFS code to register all the
objects that they want to have appear in the directory, and then have
the sunrpc code call them back to actually create/destroy their pipefs
dentries when the rpc_client creates/destroys the parent.

The clnt-&gt;cl_principal is being used exclusively to store the service

is stored only in the RPCSEC_GSS-specific code.

In the gss-proxy case we don't want to have to reconnect at random--we
want to connect only on gss-proxy startup when we can steal gss-proxy's
context to do the connect in the right namespace.

So, provide a flag that allows the rpc_create caller to turn off the
idle timeout.
