Shin'ichiro Kawasaki 0a5aa8d161 block: fix blk_mq_attempt_bio_merge and rq_qos_throttle protection ... Commit 9d497e2941 ("block: don't protect submit_bio_checks by q_usage_counter") moved blk_mq_attempt_bio_merge and rq_qos_throttle calls out of q_usage_counter protection. However, these functions require q_usage_counter protection. The blk_mq_attempt_bio_merge call without the protection resulted in blktests block/005 failure with KASAN null- ptr-deref or use-after-free at bio merge. The rq_qos_throttle call without the protection caused kernel hang at qos throttle. To fix the failures, move the blk_mq_attempt_bio_merge and rq_qos_throttle calls back to q_usage_counter protection.
