From f8ec1062f589cdb1cffcffab1376124a1bc08500 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Wed, 21 Jan 2009 17:17:04 -0500 Subject: [PATCH] wakeup-tracer: show scheduling data in output Impact: better data for wakeup tracer This patch adds the wakeup and schedule calls that are used by the scheduler tracer to make the wakeup tracer more readable.
