I don't have any visibility on when those patches are likely to get
merged or the general practices with in flight serieses here, last time
around with some of the serieses that were in flight it was quite late
which did make it unclear if things would go in during that release
cycle at all.

The amount of churn in KVM recently and long periods where the relevant
patches are apparently pre accepted but for various not always clear
reasons not actually merged is making it quite hard to target, you're
obviously going to be a lot more in the loop so this is doubtless
clearer to you than to me. It's also been a little unclear what the
expectations are for basing things on - some people do prefer to do
their own merging for example, and while you have mentioned your in
flight serieses your communication style means that it's not been
entirely clear if you're just noting the overlap. Is it just that
refactoring series you want taking into account here or are there other
in flight serieses that should be rolled into a base?
