[PATCH v9 0/6] nfsd: overhaul the client name tracking code

[Jeff Layton <jlayton@redhat.com>]

This is the ninth 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. I think this one should be closer
to what Stanislav suggested for this code.

In particular, I've done a bit more work to make this code
container-ready. One could consider this set as the opening salvo in the
effort to containerize nfsd. This one adds an initial per-namespace
nfsd_net object, and the info for the cld upcall is now stored within
that.

I have not attempted to do any work to containerize the legacy client
tracker. I envision us ripping that code out eventually as part of
the containerization effort. But we'll see...

Also, as requested by Bruce, I've broken out the patch to consolidate
the flags field and sent that yesterday in a patchset inappropriately
named:

    "nfsd: bugfixes for"

Mea culpa on that subject line, but this patchset depends on those
patches. I'd like to see these go in for 3.4 if possible.

Jeff Layton (6):
  nfsd: add nfsd4_client_tracking_ops struct and a way to set it
  sunrpc: create nfsd dir in rpc_pipefs
  nfsd: add a per-net-namespace struct for nfsd
  nfsd: add a header describing upcall to nfsdcld
  nfsd: add the infrastructure to handle the cld upcall
  nfsd: add notifier to handle mount/unmount of rpc_pipefs sb
