I don't see a problem here, but I'm no expert at sysfs / character devices.
Alan, Greg, anyone else see any problems with how this character device is
created / destroyed?

This seems like something normally done via a control device that is addressible via bsg.

This is -not- a NAK, but maybe the storage folks have a different preference for an admin-command path.
