Hi Steven, Following your comments in [1], I reworked the patches. I agree its much cleaner now. Please check them out and thanks.
Android systrace viewer heavily depends on the tgid to group tasks. tgid is also useful for analyzing traces and generating analysis results for groups of tasks. Also Michael Sartain said he also has a need for it and helped test the series (I have added him to CC).
