Joel Becker 70526b6744 [PATCH] configfs: Pin configfs subsystems separately from new config_items. ... configfs_mkdir() creates a new item by calling its parent's ->make_item/group() functions. Once that object is created, configfs_mkdir() calls try_module_get() on the new item's module. If it succeeds, the module owning the new item cannot be unloaded, and configfs is safe to reference the item. If the item and the subsystem it belongs to are part of the same module, the subsystem is also pinned. This is the common case. However, if the subsystem is made up of multiple modules, this may not pin the subsystem. Thus, it would be possible to unload the toplevel subsystem module while there is still a child item. Thus, we now try_module_get() the subsystem's module. This only really affects children of the toplevel subsystem group. Deeper children already have their parents pinned.
