dd->async_depth is initialized to 0 now, functionally I think it's the same as q->nr_requests. And I do explain this in commit message, maybe it's not clear?
It would be good to add a comment in the source code that explains that __blk_mq_get_tag() does not restrict tag allocation if dd->async_depth is zero because that causes data->shallow_depth to be zero. Thanks, Bart.
