Can someone please tell me what actual benefits we get from retrieving an parsing this in the kernel instead of in userspace. Just adding more heuristics made your code grow by 150% since Thursday. I'm really worried about incomplete heuristics in the kernel because the process for updating them is much more involved than simply doing an update to a user package. Please define what you're trying to achieve first, because if it's just the best persistent name for the device it might be better to reverse all of this and have a user writeable field in SCSI that udev populates after it does all the heuristic stuff. Is it a range (like name + transport ID + other stuff) in which case we might get additional plug ins to do that.
