From 43780b87fa799ae65df11d89d4539d8d6a7c67eb Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Sun, 1 Jul 2007 12:13:22 -0400 Subject: SUNRPC: Add a convenient default for the hostname when calling rpc_create() A couple of callers just use a stringified IP address for the rpc client's hostname. Move the logic for constructing this into rpc_create(), so it can be shared.
