The problem I am seeing is that many work items can be queued up for the same lun before it goes away. The single threaded queue would have to allow for only a queue of one and no more. Either that or each work item for a particular lun must have the same memory address so it gets rejected if it you try to queue a remove to the same lun twice.
Maybe I am not understanding your suggestion correctly.
Thanks,
Cathy
