We'd like to prevent local buffer overflows caused by malicious or broken servers. New xdr_stream style decoders can do that. For efficiency, we also eventually want to be able to pass xdr_streams from call_decode() to all XDR decoding functions, rather than building an xdr_stream in every XDR decoding function in the kernel. Static helper functions are left without the "inline" directive. This allows the compiler to choose automatically how to optimize these for size or speed.
