From bf2695516db982e90a22fc94f93491b481796bb1 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 14 Dec 2010 14:59:29 +0000 Subject: SUNRPC: New xdr_streams XDR decoder API Now that all client-side XDR decoder routines use xdr_streams, there should be no need to support the legacy calling sequence [rpc_rqst *, __be32 *, RPC res *] anywhere. We can construct an xdr_stream in the generic RPC code, instead of in each decoder function. This is a refactoring change. It should not cause different behavior.
