Not module "unplug" (I've never heard it called that before). A module with a module_init() but no module_exit() can only be added to a running kernel, and never removed. That's intentional behaviour. However, if you're talking about hot-unplug, presumably you're talking about _CPU_ hot-unplug, and that's something the code should definitely handle irrespective of whether it's built-in or a module. The two issues are entirely separate. -- FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
