[GIT PULL] nfsd changes for 5.3

[J. Bruce Fields]

Please pull nfsd changes for 5.3:

  git://linux-nfs.org/~bfields/linux.git tags/nfsd-5.3

Note there's a conflict with a mount API patch in the vfs tree; Stephen
Rothwell's resolution in linux-next looks good.

Highlights:

- Add a new /proc/fs/nfsd/clients/ directory which exposes some
  long-requested information about NFSv4 clients (like open files) and
  allows forced revocation of client state.

- Replace the global duplicate reply cache by a cache per network
  namespace; previously, a request in one network namespace could
  incorrectly match an entry from another, though we haven't seen this
  in production.  This is the last remaining container bug that I'm
  aware of; at this point you should be able to run separate nfsd's in
  each network namespace, each with their own set of exports, and
  everything should work.

- Cleanup and modify lock code to show the pid of lockd as the owner of
  NLM locks.  This is the correct version of the bugfix originally
  attempted in b8eee0e90f97 "lockd: Show pid of lockd for remote locks".
