Subject[PATCHv4 0/2] tracing: function graph output for preempt/irqs-off tracers
Date
hi,

I'm sending reworked version of the graph output support for
preemptirqsoff/preemptoff/irqsoff tracers.

v4:
- fixed header to display all the info as for
current irqsoff tracer
- fixed reset of the max_tr buffer during the
display-graph switch

v3:
- 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
