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.
