From: Ming Lei <ming.lei@xxxxxxxxxx> Add one new function of blk_mq_all_tag_iter so that we can iterate every allocated request from either io scheduler tags or driver tags, and this way is more flexible since it allows the callers to do whatever they want on allocated request. It will be used to implement draining allocated requests on specified hctx in this patchset.
