Subject: [PATCH v5 05/20] vhost: Reorder vhost_svq_kick
Date: Tue, 19 Jul 2022 11:56:14 +0200 [thread overview]
Message-ID: <20220719095629.3031338-6-eperezma@redhat.com> (raw)
In-Reply-To: <20220719095629.3031338-1-eperezma@redhat.com>
Future code needs to call it from vhost_svq_add.
No functional change intended.
