Li Zefan	020e5f85cb	tracing/events: Add trace_event boot option ... We already have ftrace= boot option, and this adds a similar boot option for trace events, so allow trace events to be enabled at boot, for boot debugging purpose.

Li Zefan	143c145e3a	tracing/events: Documentation updates ... - 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>	2009-05-19 10:29:21 +02:00
