Which patch from Jan? I saw one, and it had issues. Then there's a second one, which is ordered behind a series that's not in my tree and wasn't queued for 5.8. And finally, there's your series, which seemed to be a subset of Jan's patch for patch 1.
So it's really not very clear. Maybe if folks got together and actually put together a series to fix this it would be easier to get this done.
