From: Allan Stephens Date: Thu, 5 Jun 2008 00:37:34 +0000 (-0700) Subject: tipc: Optimize message initialization routine X-Git-Tag: v2.6.27-rc1~969^2~360 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=757152175666681d54d370500e41a756cfedd4fc;p=linux-2.6-omap-h63xx.git tipc: Optimize message initialization routine This patch eliminates the rarely-used "error code" argument when initializing a TIPC message header, since the default value of zero is the desired result in most cases; the few exceptional cases now set the error code explicitly.
