NAME
       xdr_init_encode - Initialize a struct xdr_stream for sending data.

SYNOPSIS
       void xdr_init_encode(struct xdr_stream * xdr, struct xdr_buf * buf, __be32 * p);

ARGUMENTS
       xdr
	   pointer to xdr_stream struct

       buf
	   pointer to XDR buffer in which to encode data

       p
	   current pointer inside XDR buffer

NOTE
       at the moment the RPC client only passes the length of our scratch buffer in the xdr_buf's header kvec. Previously this meant we needed to
       call xdr_adjust_iovec after encoding the data. With the new scheme, the xdr_stream manages the details of the buffer length, and takes care
       of adjusting the kvec length for us.
