    Is there any particular reason why LSM uses stacking?
    
    To me the possibiliy of having several, specialized modules called for
    access checks in the order they were loaded, seems very useful. If one
    denies, the operation is denied. That way, any LSMs could coexist without
    the need for stacking implementation in every one.
    
    With every LSM restricting access, security wouldn't be any lower (given
    that capable() is handled in a sensible way), right? Seems like a fairly
    clean patch.
