Oleg, I agree that is a bit complex way to fix but it can fix. However, I think we should fix bugs first, because there are bugs. I don't like to leave a bug in the kernel as it is, while we re- start discussing new approach... > Could you please look at the draft patch I sent in another email?

So, I'd like to suggest you getting these fixes into ftrace as first-aid treatment, and discuss your new series. Thank you, -- Masami HIRAMATSU IT Management Research Dept.
