RE: [PATCH] ftrace port to tracepoints (linux-next)

[Takashi Nishiie]

Hi,Mathieu

I think that it is wonderful that the source code becomes simple by 
changing kernel markers to tracepoints. 

However, it seems to forget to correct the error message.

For example.

 	if (ret) {
- 		pr_info("wakeup trace: Couldn't add marker"
+		pr_info("wakeup trace: Couldn't activate tracepoint"
 			" probe to kernel_sched_wakeup\n");
 		return ret;
 	}

Thank you,
