thank you for the review. After looking at the submitted patch again,
seems more proper to use >= as the condition:

                                                                        ^^
                                                                        >=
Would it be okay if I resend the patch with this changed and add your
Reviewed-by still? Would also fix some wording in the description and
dedent the perf report output somewhat.

Thanks,
