Thank you for this great contribution, Ruslan! :) All patches look good. I therefore added this sereis to damon/next [1] tree. If this series is not added to mm.git in short term (~1 week?), I will ask mm.git maintainer (Andrew Morton) to pick this. Andrew might want us to wait until next rc1 release, though, as apparently now we want to keep more time on stabilizing mm.git for the next merge window. Andrew, please let me know if so. 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.
