*	printk/tracing: rework console tracing	zhangwei(Jovi)	2013-04-29	1	-19/+6
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Commit 7ff9554bb578 ("printk: convert byte-buffer to variable-length record buffer") removed start and end parameters from call_console_drivers, but those parameters still exist in include/trace/events/printk.h. Without start and end parameters handling, printk tracing became more simple as: trace_console(text, len); Signed-off-by: zhangwei(Jovi) <jovi.zhangwei@huawei.com> Acked-by: Steven Rostedt <rostedt@goodmis.org> Acked-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Kay Sievers <kay@vrfy.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
*	printk/tracing: Add console output tracing	Johannes Berg	2012-02-13	1	-0/+41
	Add a printk.console trace point to record any printk messages into the trace, regardless of the current console loglevel. This can help correlate (existing) printk debugging with other tracing.
