Subject: [PATCH V5 4/4] virtio-scsi: don't let virtio core to validate used buffer length
Date: Wed, 27 Oct 2021 10:21:07 +0800 [thread overview]
Message-ID: <20211027022107.14357-5-jasowang@redhat.com> (raw)
In-Reply-To: <20211027022107.14357-1-jasowang@redhat.com>
We never tries to use used length, so the patch prevents the virtio
core from validating used length.
