With CONFIG_DYNAMIC_FTRACE=n, I see a warning:
kernel/trace/ftrace.c:240:13: warning: 'control_ops_free' defined but not used
static void control_ops_free(struct ftrace_ops *ops)
^
Add an ifdef block with CONFIG_DYNAMIC_FTRACE around that function as
it is used solely from the dynamic function tracing functions.
