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?
