Subject: [PATCH v1 1/2] scsi: ufs: unify scsi_block_requests usage
Date: Tue, 24 Dec 2019 21:01:05 +0800 [thread overview]
Message-ID: <1577192466-20762-2-git-send-email-stanley.chu@mediatek.com> (raw)
In-Reply-To: <1577192466-20762-1-git-send-email-stanley.chu@mediatek.com>
Currently UFS driver has ufshcd_scsi_block_requests() with
reference counter mechanism to avoid possible racing of blocking and
unblocking requests flow. Unify all users in UFS driver to use the
same function.
