We've had support for RO/NX on our tree for a while. I'm interested
in attending the summit to share what we've done and to see how much
of it could be mainlined.

Is that related to the code that Google have in their tree?

It's 'related' in that it covers some of the same use cases but the two were developed independently as far as I know.

Thanks,
