<pre>There is no reason to make any change upstream.
Performance improvements even for bogus metrics, especially for bogus metrics,
do not get backported as they have a much greater risk of regression than their
benefit.
If it was a regression in real-world performance, then it would be a bug. By
your own statement it is not a regression to previous kernels, and the
performance has not changed.</pre>
