Greg!

Right, okay, Ill tell you more.

For features being added, where many drivers from different subsystems get
covered at once, what they tend to do is:

A: send all patches, rely on all maintainers to merge their own crap, which is a mess

B: Have a designated merger, who merges all the changes at once, no chance of regression because it's all bundled up.


C: send drivers first, then send the feature. So then driver maintainers can merge their crap, then the main feature gets merged in merge window

I prefer B, because it's easier that way, akpm is usually des merger hence
I CCed him.

Or tip tree?

Honestly, if I had to be honest, C is a very annoying way, because of what
I said above, if driver maintainer thinks I'm some newbie idiot or
something, then what will I do? He won't merge it!
