Subject: [PATCH v2 11/19] scsi: ufs: Rename __ufshcd_transfer_req_compl()
Date: Fri,  9 Jul 2021 13:26:30 -0700	[thread overview]
Message-ID: <20210709202638.9480-13-bvanassche@acm.org> (raw)
In-Reply-To: <20210709202638.9480-1-bvanassche@acm.org>

Before patch "scsi: ufs: Optimize host lock on transfer requests send/compl
paths", the host lock was held around __ufshcd_transfer_req_compl() and the
double underscore prefix indicated this. Since the SCSI host lock is no
longer held around __ufshcd_transfer_req_compl() calls, remove the double
underscore prefix.
