Subject: [PATCH] ftrace: tracing_on to start/stop tracing
Date: Fri, 12 Aug 2011 14:30:22 +0900 [thread overview]
Message-ID: <1313127022-23830-1-git-send-email-leemgs1@gmail.com> (raw)
From: Geunsik Lim <geunsik.lim@samsung.com>
tracing_enabled option is deprecated.
To start/stop tracing, write to /sys/kernel/debug/tracing/tracing_on
without tracing_enabled. This patch is based on Linux 3.1.0-rc1
