If they're static and unreferenced then the linker will remove them. Of course, usually humans remove these because they generate warnings, unless special-things happen. We deliberately do special-things with register_cpu_notifier() so the notifier-block and the handler go away if !CONFIG_HOTPLUG_CPU. If the functions are non-static then yes, I expect we end up with them in vmlinux. There are tricks we can play with -ffunction-sections to fix that, but we don't. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
