Message-Id: <1294207674-3912-1-git-send-email-tm@tao.ma> Date: Wed, 5 Jan 2011 14:07:54 +0800 From: Tao Ma <tm@....ma> To: linux-kernel@...r.kernel.org Cc: Li Zefan <lizf@...fujitsu.com>, Randy Dunlap <rdunlap@...otime.net>, Jiri Kosina <jkosina@...e.cz> Subject: [PATCH] Documentation/trace/events.txt: Remove obsolete sched_signal_send. From: Tao Ma <boyu.mt@...bao.com> 'sched_signal_send' doesn't exist in the kernel now. Replace it with 'signal_generate' so that the example in events.txt can be executed successfully. I also change some /debug to /sys/kernel/debug which is debugfs' default mount directory now(similar to commit 52ad51e).
