3 | * struct bus_type_private - structure to hold the private to the driver core portions of the bus_type structure. | |
4 | * | |
5 | * @subsys - the struct kset that defines this bus. This is the main kobject | |
6 | * @drivers_kset - the list of drivers associated with this bus | |
7 | * @devices_kset - the list of devices associated with this bus | |
8 | * @klist_devices - the klist to iterate over the @devices_kset | |
9 | * @klist_drivers - the klist to iterate over the @drivers_kset | |
10 | * @bus_notifier - the bus notifier list for anything that cares about things | |
11 | * on this bus. | |
12 | * @bus - pointer back to the struct bus_type that this structure is associated | |
13 | * with. | |
14 | * | |
15 | * This structure is the one that is the actual kobject allowing struct | |
16 | * bus_type to be statically allocated safely. Nothing outside of the driver | |
17 | * core should ever touch these fields. | |
