Yes there is overlap between ftrace and gcov and I will help in finding and merging those bits, but as I also pointed out during review, there are also fundamental differences.
By including the gcov infrastructure upstream now, we can incrementally improve its integration with any similar mechanism _while_ people are improving their test cases and identifying more bugs based on code coverage measurements.
