From c3d8c1414573be8cf7c8fdc1e076935697c7f6af Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Tue, 6 Sep 2005 15:16:33 -0700 Subject: [PATCH] More __read_mostly variables Move some more frequently read variables that showed up during some of our performance tests as sometimes ending up in hot cachelines to the read_mostly section. Fix: Move the __read_mostly from before hpet_usec_quotient to follow the variable like the other uses of __read_mostly.
