Hi, There are many places where trace API accepts the struct request_queue* parameter which can be derived from other function parameters. This patch-series removes the struct request queue parameter from the blktrace framework and adjusts the tracepoints definition and usage along with the tracing API itself. Also with the queue parameter removed now we can merge some of the trace events with creating generic event class for bio based tarce events. Finally few of more cleanups to remove the trace_block_rq_insert() wrapper blk_mq_sched_request_inserted(), get rid of the extra parameter for trace_block_getrq, remove the blk_trace_request_get_cgid(), fix tracepoint comment header, and blk_fill_rwbs() related triggred cleanup. I've added patches after first cleanup as I scan the code for more cleanup. I think patch distribution can be better but it will be great to have some feedback as the amount of clenaup has grown bigger. Any comments are welcome.
