  NFSD: Implement the COPY call (2016-10-07 14:54:25 -0400)

----------------------------------------------------------------
Some RDMA work and some good bugfixes, and two new features that could
benefit from user testing:

Anna Schumacker contributed a simple NFSv4.2 COPY implementation.  COPY
is already supported on the client side, so a call to copy_file_range()
on a recent client should now result in a server-side copy that doesn't
require all the data to make a round trip to the client and back.

Jeff Layton implemented callbacks to notify clients when contended locks
become available, which should reduce latency on workloads with
contended locks.
