+ * There are three tracing modes:
+ * - tracefs-only, used when BPF is unavailable.
+ * - BPF-only, used when BPF is available and neither trace saving nor
+ * auto-analysis are enabled.
+ * - mixed mode, used when BPF is available and either trace saving or
+ * auto-analysis is enabled (which rely on sample collection through
+ * tracefs).
