* tracing: update Documentation on max preds limitLi Zefan2011-11-041-2/+0
| | | | | | | | | | Preds is no longer stored in a fixed-size stack. The max preds now is 2^14, and is way more than enough, so don't bother to document it.

* Documentation/trace/events.txt: Remove obsolete sched_signal_send.Tao Ma2011-01-081-4/+4
| | | | | | | | | | | | | | | '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).

| | | | | | | | | | | | | | | | | | | - fix some typos - document the difference between '>' and '>>' - document the 'enable' toggle - remove section "Defining an event-enabled tracepoint", since it's out-dated and sample/trace_events/ already serves this purpose. v2: add "Updated by Li Zefan" [ Impact: make documentation up-to-date ] Signed-off-by: Li Zefan <lizf@cn.fujitsu.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: "Theodore Ts'o" <tytso@mit.edu> LKML-Reference: <4A125503.5060406@cn.fujitsu.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
