Subject: [PATCH v2 12/16] dmaengine: bcm-sba-raid: Pre-ack async tx descriptor
Date: Tue, 1 Aug 2017 16:07:56 +0530 [thread overview]
Message-ID: <1501583880-32072-13-git-send-email-anup.patel@broadcom.com> (raw)
In-Reply-To: <1501583880-32072-1-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).
