Subject: [PATCH v3 08/17] scsi: ufs: Remove ufshcd_any_tag_in_use()
Date: Tue, 30 Nov 2021 15:33:15 -0800 [thread overview]
Message-ID: <20211130233324.1402448-9-bvanassche@acm.org> (raw)
In-Reply-To: <20211130233324.1402448-1-bvanassche@acm.org>
Use hba->outstanding_reqs instead of ufshcd_any_tag_in_use(). This patch
prepares for removal of the blk_mq_start_request() call from
ufshcd_wait_for_dev_cmd(). blk_mq_tagset_busy_iter() only iterates over
started requests.
