If anyone has any objections, please let me know. ------------------ From: Pratyush Anand commit c9fda7d6f62a6520e01652d370654c5657d3c1a1 upstream. I am not sure, why I found it during SG debugging. But, I noticed that even when req_queued list was empty, there were some request in request_list having queued flag true. If I run test second time, it first removes all request from request_list and hence busy_slot was wrongly incremented.
