[PATCH v4 0/3] tracing: Add support for recording tgid of tasks

[Joel Fernandes]

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).
