I believe you are referring to the race that is in HEAD between registering 
the device and an ioctl call coming in.  If so then this was fixed in the WPA 
branch long ago by reordering the attach code so the device is not registered 
until after the state is setup.  Your patch for HEAD was a bandaid so I 
didn't apply it.
