The script call is quite expensive (it does multiple things, including checking device-mapper, qubesdb etc). Don't call it for devices we (or else) already excluded earlier. This is the most relevant for dom0, where udev "change" event is triggered quite often, for multiple LVM volumes - all excluded, because being VM's disks.
