Subject: [Qemu-devel] [PATCH v2 4/7] virtio-blk: Export request handling functions to dataplane
Date: Tue, 17 Jun 2014 14:32:07 +0800 [thread overview]
Message-ID: <1402986730-25642-5-git-send-email-famz@redhat.com> (raw)
In-Reply-To: <1402986730-25642-1-git-send-email-famz@redhat.com>
So that dataplane can use virtio_blk_handle_request and
virtio_submit_multiwrite.
