+Subject: [PATCH] virgl: fix checking fences
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When calling virgl_fence_wait() with timeout=0,
+virgl_{drm,vtest}_resource_is_busy() is called. However, it returns TRUE
+for a busy resource, whereace virgl_fence_wait() should return TRUE for
+a completed (non-busy) resource.
+
+This fixes running supertuxkart in a VM (I could not reproduce locally
+with vtest though there is a similar fix)
