[PATCHv3 0/2] tracing: function graph output for preempt/irqs-off tracers

[Jiri Olsa <jolsa@redhat.com>]

hi,

I reworked it based on your comments:

- the function_graph tracer should have the same output
  as current version even with events enabled,
  unless I missed something again ;)

- I gave up the idea of function_graph events,
  since it was unsuitable for outputing other
  events as comments "/* */"

- I'm not including the raw function_graph for now


attached patches:
- 1/2 graph output support for irqsoff tracer
- 2/2 graph output support for preemptirqsoff/preemptoff tracers

plz let me know what you think

wbr,
jirka
