Why did I look at that in the first place? But as I did, I just have to
say, it's just consistent trainwreck engineering. Remove working code first
and then add new one.

Hell NO! This is not how it works. We add new infrastructure - if required
with some extra temporary helpers - while keeping the existing
functionality intact. Then we convert the users of the old infrastructure
over and when the last user is gone, we remove that including all temporary
helpers.

That's not something fundamentally new. It's documented all over the place.

Thanks,

tglx
