driver\ntag failure.\n\nThen in __sbitmap_queue_wake_up(), waitqueue_active() may not observe\nthe added waiter in blk_mq_mark_tag_wait() and wake up nothing, meantime\nblk_mq_mark_tag_wait() can't get driver tag successfully.\n\nThis issue can be reproduced by running the following test in loop, and\nfio hang can be observed in < 30min when running it on my test VM\nin laptop.\n\n\tmodprobe -r
