Subject: [PATCH 3/6] dma: bcm-sba-raid: pre-ack async tx descriptor
Date: Wed, 26 Jul 2017 11:06:41 +0530 [thread overview]
Message-ID: <1501047404-14456-4-git-send-email-anup.patel@broadcom.com> (raw)
In-Reply-To: <1501047404-14456-1-git-send-email-anup.patel@broadcom.com>
We should pre-ack async tx descriptor at time of
allocating SBA request (just like other RAID drivers).
