- array until after the device has been registered, owing to the
- fact that we can't know the minor device number until after 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

- 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
