It will be added in part 2 of the series.  See v3:
https://lore.kernel.org/qemu-devel/20201112214350.872250-35-ehabkost@xxxxxxxxxx/

I don't know what else I could say about its purpose, in addition
to what I wrote above, and the comment below[1].

If you are just curious about the callback and confused because
it is not anywhere in this series, I can just remove the
paragraph above from the commit message.  Would that be enough?
