It is an extension to the existing userspace-kernel interface: a size reduction of an underlying device is detected on reload and triggers the removal of metadata relating to the removed portion of the device. Another interface might for example require a message to be sent to set a threshold above which the device is 'cleaned' until there is no metadata pointing beyond that point. A subsequent reload using the smaller underlying device would not then need to trigger any metadata removal: it would already have been removed.
