Well, thanks for your opinion.  Here is mine:

The iwlwifi drivers have been hitting these problems for months,
and I have seen no effort by your team to address the problems.
It is possible that your team is working on them behind closed doors
and will eventually throw something over the wall to us.  I'm tired
of waiting for that, and I imagine that hordes of iwlagn users are
tired of waiting as well.

Johannes has presented us with plausible fixes, and people are
reporting that the patches work for them.  I can merge these patches,
or wait/hope/pray for some to come from your team.  Experience suggests
that if fixes do come from your team that they will either be buried
in some monster patch that largely addresses something else, or
that the patches will arrive with a changelog that is terse and/or
unintelligble.  Subsequently, I am not optimistic about waiting.

I think Johannes cited four different bugzilla.kernel.org entries
between those two patches.  What is your team doing to address
those bugs?

Obviously, I still think that those patches should be merged.

You are welcome to submit patches that address your hardware issue
and which do not introduce locking problems.

Thanks,

John
