Merge tag 'nfs-for-3.12-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

Pull NFS client bugfixes (part 2) from Trond Myklebust:
 "Bugfixes:
   - Fix a few credential reference leaks resulting from the
     SP4_MACH_CRED NFSv4.1 state protection code.
   - Fix the SUNRPC bloatometer footprint: convert a 256K hashtable into
     the intended 64 byte structure.
   - Fix a long standing XDR issue with FREE_STATEID
   - Fix a potential WARN_ON spamming issue
   - Fix a missing dprintk() kuid conversion

  New features:
   - Enable the NFSv4.1 state protection support for the WRITE and
     COMMIT operations"
