Hi James,
Patch 1 and Patch 2 merged into next-scsi and 3.9.0 on 4/6/13 but
Patch3 is missed in both of next-scsi
and 3.9.0 tree. Can you merge Patch 3 or I need to re-send the Patch3?
Thanks for your help!
Wendy

Defined target_ids,array_ids and vsets_ids as unsigned long to avoid
target_destroy accessing memory after it was freed.
