In meantime, commit 0e4a459f56c3 ("tracing: Remove unnecessary DEBUG_FS dependency") removed the dependency between CONFIG_DEBUG_FS and CONFIG_TRACING, so CONFIG_DEBUG_FS is no longer enabled in default builds. Enable it again explicitly, as debugfs support is essential for various automated testing tools.
