After checking the request_queue argument of funtion blk_execute_rq_nowait, I now added three more patches, one to remove the same argument from blk_execute_rq and other two to change the at_head argument from blk_exeute_rq_{nowait} from int to bool. Original patch can be checked here[1]. After this patch gets merged, my plan is to analyse the usage the gendisk argument, is being set as NULL but the majority of callers.
