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> 2012-02-13T18:46:05+00:00 Johannes Berg johannes.berg@intel.com 2011-11-24T19:03:08+00:00 urn:sha1:95100358491abaa2e9a5483811370059bbca4645 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.
