From 13c28be58c2bdb12e554e01b0e35621060068b11 Mon Sep 17 00:00:00 2001 From: SEO HOYOUNG Date: Thu, 11 Apr 2024 16:14:44 +0900 Subject: scsi: ufs: core: Changing the status to check inflight ufshcd_cmd_inflight() is used to check whether or not a command is in progress. Make it skip commands that have already completed by changing the !blk_mq_request_started(rq) check into blk_mq_rq_state(rq) != MQ_RQ_IN_FLIGHT. We cannot rely on lrbp->cmd since lrbp->cmd is not cleared when a command completes.
