Looks good to me, thank you.

I applied  this series to damon/next [1] tree.  We are now quite close to next
merge window.  It may better 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.
