I already reported that Johannes's patches worked. It was part of the earlier 
message that seemed to bug you.

I understand that the bug was in mac80211 forever; however, most wireless 
systems worked. With your change in the qdisc handling, essentially no wireless 
worked. If wireless-testing caught the same bug, we would have been "up the creek".

I didn't order John not to pull, I merely asked him. If that would have overly 
complicated his work load, he would either have ignored my request, or he would 
have told me why he couldn't do what I asked. I'm quite certain he would have 
done the latter.

In any case, the matter is now over. The patch that fixes the problem (mostly) 
is in the things that John pushed to you today. Once you do your thing, then 
they will be in mainline too. Until that happens, I have a patch to make 
mainline work for me and I can go on looking for other problems. So far, no new 
ones have appeared. I still get the possible recursive locking warning, but I 
know it is harmless.
