 NFS client updates for Linux 4.10
 
 Highlights include:
 
 Stable bugfixes:
  - Fix a pnfs deadlock between read resends and layoutreturn
  - Don't invalidate the layout stateid while a layout return is outstanding
  - Don't schedule a layoutreturn if the layout stateid is marked as invalid
  - On a pNFS error, do not send LAYOUTGET until the LAYOUTRETURN is complete
  - SUNRPC: fix refcounting problems with auth_gss messages.
 
 Features:
  - Add client support for the NFSv4 umask attribute.
  - NFSv4: Correct support for flock() stateids.
  - Add a LAYOUTRETURN operation to CLOSE and DELEGRETURN when return-on-close
    is specified
  - Allow the pNFS/flexfiles layoutstat information to piggyback on LAYOUTRETURN
  - Optimise away redundant GETATTR calls when doing state recovery and/or
    when not required by cache revalidation rules or close-to-open cache
    consistency.
  - Attribute cache improvements
  - RPC/RDMA support for SG_GAP devices
 
 Bugfixes:
  - NFS: Fix performance regressions in readdir
  - pNFS/flexfiles: Fix a deadlock on LAYOUTGET
  - NFSv4: Add missing nfs_put_lock_context()
  - NFSv4.1: Fix regression in callback retry handling
  - Fix false positive NFSv4.0 trunking detection.
  - pNFS/flexfiles: Only send layoutstats updates for mirrors that were updated
  - Various layout stateid related bugfixes
  - RPC/RDMA bugfixes
