svn commit: r228401 - projects/nfsv4.1-client/sys/rpc

New Revision: 228401
URL: http://svn.freebsd.org/changeset/base/228401

Log:
  Define a new CLSET_BACKCHANNEL for the kernel rpc. This can
  be used to set up a backchannel on a TCP RPC socket. A backchannel
  allows RPC messages to travel in the opposite direction, with
  an RPC request from the server to client and an RPC reply
  from the client to server. This is used by NFSv4.1 for callback RPCs.
