Comment 13 for bug 1734130

I believe the best way forward is to postpone this request to 18.10, which will be based on the 4.16 (or later) kernel.
Then it will be included in the tools packages, and arrive in 18.04 via -hwe kernel, verbantim.
In the meantime, it is quite trivial to get that single script onto systems, by downloading it from kernel.org browsing.
There are very little incentives to maintain backports onto v4.15 of all of these recent patches, of which there probably still more to come.
