Kemeng Shi 2dc5f68fe6 blk-mq: wait on correct sbitmap_queue in blk_mq_mark_tag_wait ... [ Upstream commit 98b99e9412d0cde8c7b442bf5efb09528a2ede8b ] For shared queues case, we will only wait on bitmap_tags if we fail to get driver tag. However, rq could be from breserved_tags, then two problems will occur: 1. io hung if no tag is currently allocated from bitmap_tags. 2. unnecessary wakeup when tag is freed to bitmap_tags while no tag is freed to breserved_tags. Wait on the bitmap which rq from to fix this.
