Thinking out loud again, can we add can_destroy() callbacks?
What would the exact semantics of such a callback be? Since for proper interaction with release agents we need the subsystem to notify the framework when a subsystem object becomes releasable (currently as part of css_put()), what would a can_destroy() callback let you do that you couldn't do just by taking an extra css refcount to prevent destruction and releasing that refcount to allow destruction?
