Merge tag 'nfsd-4.17' of git://linux-nfs.org/~bfields/linux

Pull nfsd updates from Bruce Fields:
 "Chuck Lever did a bunch of work on nfsd tracepoints, on RDMA, and on
  server xdr decoding (with an eye towards eliminating a data copy in
  the RDMA case).

  I did some refactoring of the delegation code in preparation for
  eliminating some delegation self-conflicts and implementing write
  delegations"
