Subject: [PATCH V2 08/12] virtio_ring: fix typos in vring_desc_extra
Date: Tue, 12 Oct 2021 14:52:23 +0800	[thread overview]
Message-ID: <20211012065227.9953-9-jasowang@redhat.com> (raw)
In-Reply-To: <20211012065227.9953-1-jasowang@redhat.com>

We're actually tracking descriptor address and length instead of the
buffer.
