From b80d72261aec5e763a76497eba5fddc84833a154 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 6 May 2011 15:06:01 -0700 Subject: [PATCH] ipv4: Initialize on-stack cork more efficiently. ip_setup_cork() explicitly initializes every member of inet_cork except flags, addr, and opt. So we can simply set those three members to zero instead of using a memset() via an empty struct assignment. Signed-off-by: David S.
