Thank you for making this series well done like this!

But definitely that is no blocker. For the series, Reviewed-by: SJ Park This series is applied to damon/next [1] tree. If this series is not added to mm.git in short term (~3 days?), I will ask mm.git maintainer (Andrew Morton) to pick this. In the case, I will update patch 1 to do what I mentioned as preferred change if you don't mind. So, no action from your side is needed for now. If it seems I also forgot doing that or you cannot wait for my action, please feel free to directly ask that to Andrew.
