Merge branch 'for-3.18' of git://linux-nfs.org/~bfields/linux

Pull nfsd updates from Bruce Fields:
 "Highlights:

   - support the NFSv4.2 SEEK operation (allowing clients to support
     SEEK_HOLE/SEEK_DATA), thanks to Anna.
   - end the grace period early in a number of cases, mitigating a
     long-standing annoyance, thanks to Jeff
   - improve SMP scalability, thanks to Trond"
