Thanks Kirti/Neo for your nice work! We are integrating this common
framework with KVMGT. Once ready it'll be released as an experimental
feature in our next community release.

One curious question. There are some additional changes in our side.
What is the best way to collaborate our effort before this series is
accepted in upstream kernel? Do you prefer to receiving patches from
us directly, or having it hosted some place so both sides can contribute?

Of course we'll conduct high-level discussions of our changes and reach
agreement first before merging with your code.

Thanks
Kevin
