From d6783b2b6c4050df0ba0a84c6842cf5bc2212ef9 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 26 Jan 2010 14:04:04 -0500 Subject: [PATCH] SUNRPC: Bury "#ifdef IPV6" in svc_create_xprt() Clean up: Bruce observed we have more or less common logic in each of svc_create_xprt()'s callers: the check to create an IPv6 RPC listener socket only if CONFIG_IPV6 is set. I'm about to add another case that does just the same. If we move the ifdefs into __svc_xpo_create(), then svc_create_xprt() call sites can get rid of the "#ifdef" ugliness, and can use the same logic with or without IPv6 support available in the kernel.
