[PATCH v7 0/5] nfsd: overhaul the client name tracking code

[Jeff Layton <jlayton@redhat.com>]

This is the seventh iteration of this patchset. The primary motivation
for the respin here is to deal with the changes introduced by Stanislav's
"namespacification" of rpc_pipefs.

My conversion here is fairly simple-minded. Since most of the existing
nfsd code works under the aegis of "init_net", this patchset makes the
new code do basically the same thing.

I've not done any real work to make this do different pipes for different
namespaces or anything. As a result, the initialization of the client
tracking will currently fail if rpc_pipefs isn't mounted.

Comments or suggestions on this are welcome. I'm still trying to wrap
my brain around how all of this namespace stuff is supposed to work,
so it's quite possible I've overlooked something. In particular, I'd
like Stanislav's feedback since he's done the bulk of the rpc_pipefs
namespace work so far.

An earlier version of this patchset can be viewed here. That set also
contains a more comprehensive description of the rationale for doing
this:

Jeff Layton (5):
  nfsd: add nfsd4_client_tracking_ops struct and a way to set it
  sunrpc: create nfsd dir in rpc_pipefs
  nfsd: convert nfs4_client->cl_cb_flags to a generic flags field
  nfsd: add a header describing upcall to nfsdcld
  nfsd: add the infrastructure to handle the cld upcall
