14 The trace-cmd(1) reset command turns off all tracing of Ftrace. This will

15 The trace-cmd(1) stop is a complement to 'trace-cmd-start(1)'. This will

13 -----------
14 The trace-cmd(1) stack enables the Ftrace stack tracer within the kernel.
21 To enable the stack tracer, use the option *--start*, and to disable
22 the stack tracer, use the option *--stop*. The output will be the maximum
