ftrace-graph: show latency-format on print_graph_irq()
On the function_graph tracer, the print_graph_irq() function prints a
trace line with the flag ==========> on an irq handler entry, and the
flag <========== on an irq handler return.
But when the latency-format is enable, it is not printing the
latency-format flags, causing the following error in the trace output:
0) ==========> |
0) d... | smp_apic_timer_interrupt() {
This patch fixes this issue by printing the latency-format flags when
it is enable.
