87 	Select function tracer and set function filter on the given
88 	function (or a glob pattern). Multiple functions can be given
95 	Select function tracer and do not trace functions given by the
108 	Select function_graph tracer and set graph filter on the given
110 	functions executed from the given function. This can be used more
117 	given function (or a glob pattern). Like -G option, this is useful
119 	executed from the given function. This can be used more than once to
157 	Set function filter on the given function (or a glob pattern).
158 	Multiple functions can be given by using this option more than once.
164 	Do not trace functions given by the argument.  Like -T option, this
170 	Set graph filter on the given function (or a glob pattern). This is
171 	useful to trace for functions executed from the given function. This
177 	Set graph notrace filter on the given function (or a glob pattern).
179 	disables tracing for function executed from the given function. This
