Subject: [PATCH V2 12/12] virtio-scsi: don't let virtio core to validate used buffer length
Date: Tue, 12 Oct 2021 14:52:27 +0800 [thread overview]
Message-ID: <20211012065227.9953-13-jasowang@redhat.com> (raw)
In-Reply-To: <20211012065227.9953-1-jasowang@redhat.com>
We never tries to use used length, so the patch prevents the virtio
core from validating used length.
