Merge tag 'nfs-for-3.6-4' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

Pull NFS client bugfixes from Trond Myklebust:

 - Final (hopefully) fix for the range checking code in NFSv4 getacl.
   This should fix the Oopses being seen when the acl size is close to
   PAGE_SIZE.
 - Fix a regression with the legacy binary mount code
 - Fix a regression in the readdir cookieverf initialisation
 - Fix an RPC over UDP regression
 - Ensure that we report all errors in the NFSv4 open code
 - Ensure that fsync() reports all relevant synchronisation errors.
