A symbol's value won't be recalc-ed until we save config file or enter the menu where the symbol sits. So If I enable OPTIMIZE_FOR_SIZE, and search FUNCTION_GRAPH_TRACER: Symbol: FUNCTION_GRAPH_TRACER [=y] Prompt: Kernel Function Graph Tracer Defined at kernel/trace/Kconfig:140 Depends on: ... [=y] && (!X86_32 [=y] || !CC_OPTIMIZE_FOR_SIZE [=y]) ... From the dependency it should result in FUNCTION_GRAPH_TRACER=n, but it still shows FUNCTION_GRAPH_TRACER=y.
