This is to have a consistent view of all graph tracer options.
The original option '--graph-depth' is marked as deprecated.

This can be used more than once to specify multiple functions.
It will be passed to 'set_graph_notrace' in tracefs.
--D::
---graph-depth=::
- Set max depth for function graph tracer to follow
-
--graph-opts::
List of options allowed to set:
nosleep-time - Measure on-CPU time only for function_graph tracer.
noirqs - Ignore functions that happen inside interrupt.
verbose - Show process names, PIDs, timestamps, etc.
thresh=<n> - Setup trace duration threshold in microseconds.
+ depth=<n> - Set max depth for function graph tracer to follow.
