You still have zero, absolutely zero facts. _What_ is screwed?

That's not true. I would not mind such a framework. What I opposed was
you claiming that you can _proof_ data correctness. Verifying data
integrity and proof are two different things.

Bullshit.

Please stop misquoting me. _You_ claim that if you have the states down
100% from the specs, then your driver is proofen correct. I say that
believing that is an illusion, only in a perfect world with perfect
hardware would that be the case.

Again, I've _never_ made such claims. I have the tools, yes, and they
are handy at times.

I agree.

Strictly a cleanup, what's your point?

I did it now because it's easy to do, comprende? It can be done cleanly
because elv_next_request is there now.

s/single sector/single segment. And that temp mapping is done for _PIO_
for christ sakes, I challenge you to show me that being a bottleneck in
any way at all. Red herring.

Tried reading the source?

That part isn't even started yet, block_ioctl is just to show that
rq->cmd[] and ide-cd does work with passing packet commands around.

Again, what are you talking about?

Congratulations on spending so much time writing an email with very
little factual content. Here's an idea -- try backing up your statements
and claims with something besides hot air.
