Subject: [RFC v2 9/9] vfio: use imported uAPI header
Date: Wed, 3 Sep 2025 17:17:59 +0200 [thread overview]
Message-ID: <20250903151800.1965006-10-david.marchand@redhat.com> (raw)
In-Reply-To: <20250903151800.1965006-1-david.marchand@redhat.com>
Now that we have a v6.16 header in DPDK, we can remove all remaining
wrappers around VFIO uapi.
Signed-off-by: David Marchand <david.marchand@redhat.com>
