Subject: [PATCH 06/22] vhost: Reorder vhost_svq_last_desc_of_chain
Date: Fri,  8 Jul 2022 12:49:57 +0200	[thread overview]
Message-ID: <20220708105013.1899854-7-eperezma@redhat.com> (raw)
In-Reply-To: <20220708105013.1899854-1-eperezma@redhat.com>

SVQ is going to store it in SVQElement, so we need it before add functions.
