Hi David,

So the version I have of this in linux-next has not been updated since Dec 2 and is based on v4.4-rc1. The version above is based on v4.4-rc6 and has extra commits ... Did someone forget to update the xen-tip/linux-next branch?

Cheers,

Yes.

Ideally I'd like the linux-next branch in ../xen/tip.git to be symbolic reference to the current for-linus-x.y branch so I do not have to remember to push to two different branches. I can't see a way to do this though.

David

You're using tags for the pull request though, so do you need the for-linus-x.y branch at all?

I've stopped using them, and instead just push to next and ask Linus to pull a tag. That also avoids any possibility of the for-linus-x.y branch getting out of sync with the for-linus-x.y tag.

cheers
