Currently the core module does not hold any reference to component modules. Hence, a component could be unloaded from the system anytime. Even if the configuration interface is still being populated with configfs items/groups. User space then has no chance to fix the usage count by calling rmdir on such a config item/group, as the respective directory does not exist anymore. In this situation the core module cannot be unloaded anymore. This patch set fixes this issue by holding a reference as long as the configfs items exist.
