The patch got elaborated and discussed publicly (successfully or not) by following your instructions.

We all sure had a communication issue here.

What you thought it was an (implicit) NAK for the _initial_ version of the patch, others took that as "fix-those-concerns-and-its-fine".
And the expressed concerns where addressed later in the merged patch, sub-optimally (not crappily).

Looking at your new "[PATCH] b43: Optimize PIO scratchbuffer usage" to address the changes introduced by the merged patch, the merged solution is not that _blatantly_ far from your solution.
The patch would have probably got there in one iteration if you have had the chance again to express your new concerns about v2.

I'm sure we can avoid this in the future by being a bit more explicit.

Thanks,
Albert
