When you constantly go silent it looks like you are deliberately delaying
the patches - which you have a long history of doing.  Are you deliberately
delaying again?

What are you plans for the patches?

Why do you think mmc work is so unimportant it can be left to whenever you
deign to get around to it?

Rubbish!  I gave a very good reason for keeping the CQE code in - it is
designed to work together.  I also pointed out that it is trivial to see the
CQE code and that it is all '+' lines anyway.

But not one question in response!  Where is a single example of why it is
difficult like it is.  Where are the questions!  Not even a request for
documentation!  How I am supposed to know what you do or don't understand if
you don't ask any questions! There is no evidence that you guys have read a
single line!

So, what are your plans for the patches?  What don't you understand?
