Subject: [PATCH v4 07/10] vhost-user: compare mode MODE_PASTA and not MODE_PASST
Date: Fri, 31 May 2024 16:23:41 +0200 [thread overview]
Message-ID: <20240531142344.1420034-8-lvivier@redhat.com> (raw)
In-Reply-To: <20240531142344.1420034-1-lvivier@redhat.com>
As we are going to introduce the MODE_VU that will act like
the mode MODE_PASST, compare to MODE_PASTA rather than to add
a comparison to MODE_VU when we check for MODE_PASST.
