Now that rutabaga users can provide a callback for fence completion, fences no longer need to be polled on the main thread. Optional polling still occurs for Rutabaga Components that still rely on it for other purposes (e.g. virglrenderer for GL query checking). Also, use a BTreeMap rather a HashMap since we only expect a dozen or so entries at most. In such cases, a BTreeMap is faster. * v1 (lfrb@collabora.com): remove all polling + add async_cb * v2 (ryanneph@google.com): re-introduce optional polling to fix virglrenderer that relies on it for GL query checking. * v3 (ryanneph@google.com): replace timer-based polling with eventfd-based poll() signaling for components that want to use it.
