Subject: [PATCH 8/8] vhost-user: compare mode MODE_PASTA and not MODE_PASST
Date: Mon, 27 May 2024 11:10:30 +0200	[thread overview]
Message-ID: <20240527091030.772228-9-lvivier@redhat.com> (raw)
In-Reply-To: <20240527091030.772228-1-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.
