 "Highlights include:

  Stable fixes:
   - fix an NFSv4.1 state renewal regression
   - fix open/lock state recovery error handling
   - fix lock recovery when CREATE_SESSION/SETCLIENTID_CONFIRM fails
   - fix statd when reconnection fails
   - don't wake tasks during connection abort
   - don't start reboot recovery if lease check fails
   - fix duplicate proc entries

  Features:
  - pNFS block driver fixes and clean ups from Christoph
  - More code cleanups from Anna
  - Improve mmap() writeback performance
  - Replace use of PF_TRANS with a more generic mechanism for avoiding
    deadlocks in nfs_release_page"
