Also is it possible to use "enable sched:*" and
Adding new control events to enable/disable specific event.
The interface string for control file are:
'enable-'
'disable-'
when received the command, perf will scan the current evlist
for and if found it's enabled/disabled.
Example session:
terminal 1:
# mkfifo control ack perf.pipe

It makes sense to check that evsel_name still points
into cmd_data buffer after assigning to event name.
right, will add that
