And the v1 is available [1] at mailing list.

Thank you for adding this changelog.  Please add links [2] to the previous
revisions too, from next time.  For other readers, v1 

This patch is applied to damon/next [3] tree.  If this patch is not added to
mm.git in short term (~1 week?), I will ask mm.git maintainer (Andrew Morton)
to pick this.  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.
