Thank you for making this series well done like this!

I'd prefer handling 'total' underflow and returning 10,000 instead of INT_MAX
from damos_hugepage_mem_bp() corner cases.  But definitely that is no blocker.
For the series,

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.
