    Pull NFS client updates for Linux 3.4 from Trond Myklebust:
     "New features include:
       - Add NFS client support for containers.
         This should enable most of the necessary functionality, including
         lockd support, and support for rpc.statd, NFSv4 idmapper and
         RPCSEC_GSS upcalls into the correct network namespace from which
         the mount system call was issued.
       - NFSv4 idmapper scalability improvements
         Base the idmapper cache on the keyring interface to allow
         concurrent access to idmapper entries.  Start the process of
         migrating users from the single-threaded daemon-based approach to
         the multi-threaded request-key based approach.
       - NFSv4.1 implementation id.
         Allows the NFSv4.1 client and server to mutually identify each
         other for logging and debugging purposes.
       - Support the 'vers=4.1' mount option for mounting NFSv4.1 instead of
         having to use the more counterintuitive 'vers=4,minorversion=1'.
       - SUNRPC tracepoints.
         Start the process of adding tracepoints in order to improve
         debugging of the RPC layer.
       - pNFS object layout support for autologin.
      Important bugfixes include:
       - Fix a bug in rpc_wake_up/rpc_wake_up_status that caused them to
         fail to wake up all tasks when applied to priority waitqueues.
       - Ensure that we handle read delegations correctly, when we try to
         truncate a file.
       - A number of fixes for NFSv4 state manager loops (mostly to do with
         delegation recovery)."
