'just to remove a module' is very, very rare, on the timescale of most kernel ops. Almost no distro does it. Furthermore, because we want to do CPU-hotplug that way, we really want to make freeze_processes()/unfreeze_processes() 'instantaneous' to the human - and it is that already. (if it isnt in some case we can make it so) Ingo - 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/
