Allow vendors to obtain a list of modules loaded at given time. Vendor modules are able to register on part of notifier chain (register_module_notifer), but a vendor module would never see modules which are loaded before the one which registers on the notifier chain. The kernel doesn't offer load order control, so a hook is necessary to iterate through currently loaded kernel modules.
