    Linus Torvalds authored
    Pull nfsd updates from Bruce Fields:
     "This consists mostly of nfsd container work:
    
      Scott Mayhew revived an old api that communicates with a userspace
      daemon to manage some on-disk state that's used to track clients
      across server reboots. We've been using a usermode_helper upcall for
      that, but it's tough to run those with the right namespaces, so a
      daemon is much friendlier to container use cases.
    
      Trond fixed nfsd's handling of user credentials in user namespaces. He
      also contributed patches that allow containers to support different
      sets of NFS protocol versions.
    
      The only remaining container bug I'm aware of is that the NFS reply
      cache is shared between all containers. If anyone's aware of other
      gaps in our container support, let me know.
    
      The rest of this is miscellaneous bugfixes"
