configfs, like sysfs, does not support ->open() or ->release() callbacks. And it shouldn't. The point is to hide the complexity and make it easier to plug into. A client object should not ever have to know or care that it is being controlled by a filesystem. It only knows that it has a tree of items with attributes that can be set or shown.
