Subject: [PATCH 3/3] rutabaga_gfx: fix stale cross-domain keymap resources
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
when running vulkaninfo and other apps it seems that this resource
is requested multiple times and it fails after the first time.
After this patch vulkaninfo no longer produces any qemu errors.
