Well, no.  The first conversion patch that I saw was posted after the
merge window had already closed, on 8 April.

That's what we call a "regression". :)

If you remove the legacy interfaces then even a build test will point
out the drivers that still need to be converted. :)

It does matter, actually.

What's so special about 2.6.30 that it matters whether the legacy
interfaces are still there or not?

As for blocking development, you can remove the legacy interfaces
today in your next branch and get on with development immediately.  So
the "blocking development" argument has zero relevance to what goes
into Linus' tree for 2.6.30.  Even if you got the legacy interfaces
removed for 2.6.30 you still wouldn't be able to get any new features
based on that into 2.6.30.

And this is a particularly bad time to be hastily trying to get
powermac driver changes upstream, since Ben H. is on vacation.

Can we compromise on this?  I'll do everything I reasonably can to
help you get the powermac driver patches tested and working before the
2.6.31 merge window, if you agree to leave the drivers and interfaces
in Linus' tree as they are for 2.6.30.

Paul.
