Subject: [RFC v2 7/7] vduse: bump version number
Date: Thu,  7 Aug 2025 13:57:52 +0200	[thread overview]
Message-ID: <20250807115752.1663383-8-eperezma@redhat.com> (raw)
In-Reply-To: <20250807115752.1663383-1-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.
