OK. What's a safe way to iterate over the devices in the presence of hotplug, then? I assume it's list_for_each_mumble; I just don't know what mumble is :-) > Also you only do this when the module is loaded, so you won't handle > devices that are hot-plugged later.

There's nothing in LDD3 about this, so I'm kind of in the dark. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
