Before today I would have said no - as I think the rework of these
patches, the addition of a new hypervisor, review, etc in four days
would be highly unlikely - and that meant you would be so busy
working towards a deadline and very likely missing it.

But we are slipping the schedule due to another issue so the RC0 will
move from October 15th to October 25th.

That means you will have some breathing room to work this out.

So lets see those patches and then evaluate them case-by-case basis.
Naturally before even I can give an exception on them - they have
to be OK with the maintainers.

And tested quite extensively.
