I applied  this patch to damon/next [1] tree.  We are now quite close to next
merge window.  We (mm community) want to focus on making mm.git more stabilized
and therefore ready for the next merge window, rather than adding more changes
that are not really urgent.  I understand this series is not really urgent.
Hence, Andrew might not add this patch until next -rc1 release.  In the case, I
will request adding this to mm.git after next -rc1 release.  So, no action from
your side is needed for now.  Let me know if you think this is really  urgent.
