Gentle ping for this patch series.

I tested this patch series on perf/core branch with latest commit
87b40003b17a ("perf tests: Check that complex event name is parsed
correctly"), this patch series is still valid and can pass testing.

Could you pick up them?  If you want me to resend this patch series,
please let me know.

Thanks,
Leo Yan
