How does your tool > hook into queue_command? The code could be found at http://blog.chinaunix.net/u/15278/showart_1966962.html. You need do some modification according your kernel. It's very simple to hook the queue_command. I just backup the original function pointer somewhere and after dump, I restore it. Pls refer the code for detail.
