6b6e39a6 | 4 | * struct subsys_private - structure to hold the private to the driver core portions of the bus_type/class structure. |
c6f7e72a | 5 | * |
6b6e39a6 | 6 | * @subsys - the struct kset that defines this subsystem |
ca22e56d KS |
7 | * @devices_kset - the subsystem's 'devices' directory |
8 | * @interfaces - list of subsystem interfaces associated | |
9 | * @mutex - protect the devices, and interfaces lists. | |
6b6e39a6 KS |
10 | * |
11 | * @drivers_kset - the list of drivers associated | |
c6f7e72a GKH |
12 | * @klist_devices - the klist to iterate over the @devices_kset |
13 | * @klist_drivers - the klist to iterate over the @drivers_kset | |
14 | * @bus_notifier - the bus notifier list for anything that cares about things | |
6b6e39a6 | 15 | * on this bus. |
c6f7e72a | 16 | * @bus - pointer back to the struct bus_type that this structure is associated |
6b6e39a6 KS |
17 | * with. |
18 | * | |
6b6e39a6 KS |
19 | * @glue_dirs - "glue" directory to put in-between the parent device to |
20 | * avoid namespace conflicts | |
6b6e39a6 KS |
21 | * @class - pointer back to the struct class that this structure is associated |
22 | * with. | |
c6f7e72a GKH |
23 | * |
24 | * This structure is the one that is the actual kobject allowing struct | |
6b6e39a6 KS |
25 | * bus_type/class to be statically allocated safely. Nothing outside of the |
26 | * driver core should ever touch these fields. | |
