This _workaround_ willn't work, take_over_console will hold console_lock internal, but do_take_over_console need caller hold console_lock, then we can't rewrite do_take_over_console as a wrap base on take_over_console. But the reverse is ok. So if we have to do it, then the actual interface is do_take_over_console, and the "_workaround_" is exposing take_over_console as a wrap base on do_take_over_console. -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
