ftrace: show unlimited when traceon or traceoff has no counter
Impact: clean up The traceon and traceoff function probes are confusing to developers to what happens when a counter is not specified. This should help clear things up. # echo "*:traceoff" > set_ftrace_filter # cat /debug/tracing/set_ftrace_filter #### all functions enabled #### do_fork:traceoff:unlimited Signed-off-by: Steven Rostedt <srostedt@redhat.com>
