* All kobjects of a kset should be embedded in an identical
* type. This type may have a descriptor, which the kset points
* to. This allows there to exist sets of objects of the same
* type in different subsystems.
* A kset defines a group of kobjects. They can be individually
* different "types" but overall these kobjects all want to be grouped
* together and operated on in the same manner. ksets are used to
* define the attribute callbacks and other common events that happen to
* a kobject.
*
* A subsystem does not have to be a list of only one type
* of object; multiple ksets can belong to one subsystem. All
* ksets of a subsystem share the subsystem's lock.
*
* Each kset can support specific event variables; it can
* supress the event generation or add subsystem specific
* variables carried with the event.
* @ktype: the struct kobj_type for this specific kset
* @list: the list of all kobjects for this kset
* @list_lock: a lock for iterating over the kobjects
