        Ranges of CPUs are specified with -: 0-2.
        Default is to trace on all online CPUs.
 
+-T::
+--trace-funcs=::
+       Only trace functions given by the argument.  Multiple functions
+       can be given by using this option more than once.  The function
+       argument also can be a glob pattern.  It will be passed to
+       'set_ftrace_filter' in tracefs.

+-N::
+--notrace-funcs=::
+       Do not trace functions given by the argument.  Like -T option,
+       this can be used more than once to specify multiple functions
+       (or glob patterns).  It will be passed to 'set_ftrace_notrace'
+       in tracefs.
+
+-G::
+--graph-funcs=::
+       Set graph filter on the given function (or a glob pattern).
+       This is useful for the function_graph tracer only and enables
+       tracing for functions executed from the given function.
+       This can be used more than once to specify multiple functions.
+       It will be passed to 'set_graph_function' in tracefs.

+-g::
+--nograph-funcs=::
+       Set graph notrace filter on the given function (or a glob pattern).
+       Like -G option, this is useful for the function_graph tracer only
+       and disables tracing for function executed from the given function.
+       This can be used more than once to specify multiple functions.

+-D::
+--graph-depth=::
+       Set max depth for function graph tracer to follow
