NAME
       xdr_set_scratch_buffer - Attach a scratch buffer for decoding data.

SYNOPSIS
       void xdr_set_scratch_buffer(struct xdr_stream * xdr, void * buf, size_t buflen);

ARGUMENTS
       xdr
	   pointer to xdr_stream struct

       buf
	   pointer to an empty buffer

       buflen
	   size of 'buf'

DESCRIPTION
       The scratch buffer is used when decoding from an array of pages. If an xdr_inline_decode call spans across page boundaries, then we copy
       the data into the scratch buffer in order to allow linear access.
