- we register the device. We can't update the device mapping
- array until after the device has been registered, owing to the
- fact that we can't know the minor device number until after the
- registration succeeds. And if another thread tries to open the
- device in the window of time after registration but before the
- map is updated, then it will get back an erroneous null pointer
- and the open will result in a spurious failure. The only way to
- prevent that is to (a) be inside the mutex here before we access
- the array, and (b) cover the entire registration process later
- on with this same mutex. Thus if we get inside the mutex here,
- then we can be assured that the registration process actually
- completed correctly. This is an unhappy complication from the
- use of global data in a driver that lives in a preemptible
- environment. It sure would be nice if the video device itself
- had a means for storing and retrieving a local context pointer.
