From: Tao Ma Date: Wed, 5 Jan 2011 06:07:54 +0000 (+0800) Subject: Documentation/trace/events.txt: Remove obsolete sched_signal_send. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bfc672dcf323877228682aff79dff8ecd9f30ff8;p=linux-beck.git Documentation/trace/events.txt: Remove obsolete sched_signal_send. '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).
