10   at the moment the RPC client only passes the length of our
11   scratch buffer in the xdr_buf's header kvec. Previously this
12   meant we needed to call <code class="function">xdr_adjust_iovec</code> after encoding the
13   data. With the new scheme, the xdr_stream manages the details
14   of the buffer length, and takes care of adjusting the kvec
15   length for us.
