Browse Source 
Pull NFS client updates from Trond Myklebust:
 "Highlights include:

  Features:
   - NFSv4.1 can always retrieve and cache the ACCESS mode on OPEN
   - Optimisations for READDIR and the 'ls -l' style workload
   - Further replacements of dprintk() with tracepoints and other
     tracing improvements
   - Ensure we re-probe NFSv4 server capabilities when the user does a
     "mount -o remount"

  Bugfixes:
   - Fix an Oops in pnfs_mark_request_commit()
   - Fix up deadlocks in the commit code
   - Fix regressions in NFSv2/v3 attribute revalidation due to the
     change_attr_type optimisations
   - Fix some dentry verifier races
   - Fix some missing dentry verifier settings
   - Fix a performance regression in nfs_set_open_stateid_locked()
   - SUNRPC was sending multiple SYN calls when re-establishing a TCP
     connection.
   - Fix multiple NFSv4 issues due to missing sanity checking of server
     return values
   - Fix a potential Oops when FREE_STATEID races with an unmount

  Cleanups:
   - Clean up the labelled NFS code
   - Remove unused header <linux/pnfs_osd_xdr.h>"

  NFSv4: Remove unnecessary 'minor version' check
  NFSv4: Fix potential Oops in decode_op_map()
