Because of that, we can defer initialization until all modules are ready instead of handling it explicitly with custom init/exit functions. As a consequence of removing explicit module initialization and deferring probe until everything is ready, there's no need for custom init and exit functions. There are now module_init and module_exit calls but no real change in functionality as these init and exit functions are no longer directly called by core.
