Subject: [PATCH 0/7] perf stat: Change event enable code

hi,
while testing ftrace:function event I noticed we create
stat counters as enabled (except for enable_on_exec couters).

This way we count also filter setup and other config code
which might be crucial for some events.

Posponing the events enable once everything is ready.

The last patch is RFC as I wasn't sure there's some hidden
catch about perf_evlist__(enable|disable)_event functions
I missed.. Adrian?

thanks,
jirka

      perf tools: Use event maps directly in perf_evsel__enable
      perf tools: Introduce perf_evsel__disable function
      perf tools: Factor perf_evlist__(enable|disable) functions
      perf stat: Use perf_evlist__enable in handle_initial_delay
      perf stat: Create events as disabled
      perf stat: Move enable_on_exec setup under earlier code
      perf tools: Remove perf_evlist__(enable|disable)_event functions
