Subject: [PATCH 0/3] perf tools: Allow to enable/disable events via control pipe

hi,
adding support to enable/disable specific events via control
file via following commands:

    # echo enable-sched:sched_process_fork > control
    # echo disabled-sched:sched_process_fork > control

The code is available in here:
  git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  perf/control

thanks,
jirka
