I don\u0027t know why but that shouldn\u0027t\nbe difficult to find.\n\nI moved linux/tracepoint.h to trace/tracepoint.h as well. I think that would\nbe more easy to find the tracer headers if they are all in their common\ndirectory.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"
