Subject: [PATCH v7 13/28] ufs: core: Only call ufshcd_should_inform_monitor() for SCSI commands
Date: Thu, 30 Oct 2025 12:36:12 -0700 [thread overview]
Message-ID: <20251030193720.871635-14-bvanassche@acm.org> (raw)
In-Reply-To: <20251030193720.871635-1-bvanassche@acm.org>
ufshcd_should_inform_monitor() only returns 'true' for SCSI commands.
Instead of checking inside ufshcd_should_inform_monitor() whether its
second argument represents a SCSI command, only call this function for
SCSI commands. This patch prepares for removing the lrbp->cmd member.
