tracing: add latency format to function_graph tracer
While debugging something with the function_graph tracer, I found the need to see the preempt count of the traces. Unfortunately, since the function graph tracer has its own output formatting, it does not honor the latency-format option. This patch makes the function_graph tracer honor the latency-format option, but still keeps control of the output. But now we have the same details that the latency-format supplies. # tracer: function_graph # # _-----=> irqs-off # / _----=> need-resched # | / _---=> hardirq/softirq # || / _--=> preempt-depth # ||| / # |||| # CPU|||| DURATION FUNCTION CALLS # | |||| | | | | | | 3) d..1 1.333 us | idle_cpu(); 3) d.h1 | tick_check_idle() { 3) d.h1 0.550 us | tick_check_oneshot_broadcast(); 3) d.h1 | tick_nohz_stop_idle() { 3) d.h1 | ktime_get() { 3) d.h1 | ktime_get_ts() { Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
