From ff9aa5e56df60cc8565a93cc868fe25ae3f20e49 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 22 Aug 2006 20:06:21 -0400 Subject: SUNRPC: Eliminate xprt_create_proto and rpc_create_client The two function call API for creating a new RPC client is now obsolete. Remove it. Also, remove an unnecessary check to see whether the caller is capable of using privileged network services. The kernel RPC client always uses a privileged ephemeral port by default; callers are responsible for checking the authority of users to make use of any RPC service, or for specifying that a nonprivileged port is acceptable. Test plan: Repeated runs of Connectathon locking suite. Check network trace to ensure correctness of NLM requests and replies.
