From: Christoph Lameter Date: Fri, 17 Mar 2006 07:04:00 +0000 (-0800) Subject: [PATCH] time_interpolator: add __read_mostly X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=67890d7084085e29c51afa2514036d42643fd3cf;p=openwrt%2Fstaging%2Fblogic.git [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.
