Hmm, I thought the graph tracer depends on function tracer? Anyway, the configs should be cleaned up. I would like to make CONFIG_FTRACE just mean the function hook mechanism (mcount,fentry,etc) and not be used for the tracing system. Anyway, we can just make ftrace_regs defined outside any config for now. -- Steve
