Sorry, I answered your question too quickly.
I meant this patch should go through Russell's Patch Tracking System.

For the other patches, I think it should be picked by their respective
maintainers.
Or I can create an immutable tag (on github or kernel.org?) that will
be merged by the different sub-systems?
What would you advise?

Thanks,
Maxime
