IMHO it just expands the hack that is LUN 0, but hey, I'm biased.

Since you obviously don't want to merge it as is: my patch also avoided
spawning worker threads for this LUN 0 that end up doing nothing by
setting the backing store to bs_null - can this be merged or does it
conflict with 55b15d746fb ?
