So I absolutely *hate* how this was done.

Why the hell was it mixed in with the block layer code? It's not even
in some clean separate branch, it's just randomly in the middle of the
block code, for no obvious reason.

I'm pulling it this time, but quite frankly, next time I see this kind
of ugly AND TOTALLY POINTLESS layering violation, I will just drop the
stupid pull request.

If you want to push me cleanups that are to generic code and are in no
way specific to the block layer, fine. But I want a separate pull
request that is not in any way mixed up with block code.

In other words, this was NOT OK. This was stupid and wrong, and
violated all sanity. I can see absolutely no reason why that
smp_call_function_single_async() renaming and the other cleanups are
in the block branch. They are totally separate in every single way.

What the hell was going on here?

I agree, it should have been in its own topic branch. No real arguments there. And probably should have been split further, so only the block required parts ended up in there, and not eg the watchdog parts.
