From 213cc060797378059a28ebc5c539f3e9a80160bd Mon Sep 17 00:00:00 2001 From: Pekka J Enberg Date: Fri, 19 Dec 2008 12:08:39 +0200 Subject: ftrace: introduce tracing_reset_online_cpus() helper Impact: cleanup This patch factors out common code from multiple tracers into a tracing_reset_online_cpus() function and converts the tracers to use it.
