Who told you/anyone who wrote this code before that the 0th lun cannot be a real entry? This assumption is wrong.
Well, that particular piece of code isn't looking at the 0'th LUN, but there is code below that that is. However, the code here is generally looking for block devices, and the 0'th LUN is definitely not a block device. Given that, I'm not sure what else you would want to do with 0th LUN; can you give me some examples?
The 0th LUN can be a perfect block device.

OK, cool, I misunderstood.  Given that, can you give me the output of:

# ls -l /sys/bus/scsi/devices/3:0:0:0

Just to make sure I get the right thing?
