There must have been half a dozen attempts to send this patch series
upstream. I have tried, and others have tried. Each attempt failed with
someone else objecting for non-technical reasons (such as "we need more
reviews") or no reaction at all, and maintainers just don't pick it up.

So, yes, this patch series can only be found in downstream trees,
and it seems pointless to submit it yet again.
