From cf500bac8fd48b57f38ece890235923d4ed5ee91 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 11 Feb 2019 11:25:20 -0500 Subject: SUNRPC: Introduce rpc_prepare_reply_pages() prepare_reply_buffer() and its NFSv4 equivalents expose the details of the RPC header and the auth slack values to upper layer consumers, creating a layering violation, and duplicating code. Remedy these issues by adding a new RPC client API that hides those details from upper layers in a common helper function.
