From bfc672dcf323877228682aff79dff8ecd9f30ff8 Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Wed, 5 Jan 2011 14:07:54 +0800 Subject: 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).
