Merge branch 'for-3.17' of git://linux-nfs.org/~bfields/linux

Pull nfsd updates from Bruce Fields:
 "This includes a major rewrite of the NFSv4 state code, which has
  always depended on a single mutex.  As an example, open creates are no
  longer serialized, fixing a performance regression on NFSv3->NFSv4
  upgrades.  Thanks to Jeff, Trond, and Benny, and to Christoph for
  review.

  Also some RDMA fixes from Chuck Lever and Steve Wise, and
  miscellaneous fixes from Kinglong Mee and others"
