Subject: [PATCH v8 6/6] vduse: bump version number
Date: Thu, 30 Oct 2025 11:00:25 +0100	[thread overview]
Message-ID: <20251030100025.95113-7-eperezma@redhat.com> (raw)
In-Reply-To: <20251030100025.95113-1-eperezma@redhat.com>

Finalize the series by advertising VDUSE API v1 support to userspace.

Now that all required infrastructure for v1 (ASIDs, VQ groups,
update_iotlb_v2) is in place, VDUSE devices can opt in to the new
features.

Acked-by: Jason Wang <jasowang@redhat.com>
