From 67890d7084085e29c51afa2514036d42643fd3cf Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Thu, 16 Mar 2006 23:04:00 -0800 Subject: [PATCH] time_interpolator: add __read_mostly The pointer to the current time interpolator and the current list of time interpolators are typically only changed during bootup. Adding __read_mostly takes them away from possibly hot cachelines.
