From ab32ea5d8a760e7dd4339634e95d7be24ee5b842 Mon Sep 17 00:00:00 2001 From: Brian Haley Date: Fri, 22 Sep 2006 14:15:41 -0700 Subject: [NET/IPV4/IPV6]: Change some sysctl variables to __read_mostly Change net/core, ipv4 and ipv6 sysctl variables to __read_mostly. Couldn't actually measure any performance increase while testing (.3% I consider noise), but seems like the right thing to do. Signed-off-by: Brian Haley Signed-off-by: David S.
