Patch 1 will be only slightly different. It will only copy a few more values to 
iscsilun. its primary the inquiry code. I Would put the things we discussed in 
a second patch. But if you dont want to pull iscsi_co_is_allocated for your 
series its not needed. If you would like to have it in i can add the missing 
values and send you a patch.
