* struct bus_type_private - structure to hold the private to the driver core portions of the bus_type structure.
* @subsys - the struct kset that defines this bus. This is the main kobject
* @drivers_kset - the list of drivers associated with this bus
* @devices_kset - the list of devices associated with this bus
* @klist_devices - the klist to iterate over the @devices_kset
* @klist_drivers - the klist to iterate over the @drivers_kset
* @bus_notifier - the bus notifier list for anything that cares about things
* on this bus.
* @bus - pointer back to the struct bus_type that this structure is associated
* with.
* This structure is the one that is the actual kobject allowing struct
* bus_type to be statically allocated safely. Nothing outside of the driver
* core should ever touch these fields.
