x86/stacktrace: return 0 instead of -1 for stack ops
If we return -1 in the ops->stack for the stacktrace saving, we end up breaking out of the loop if the stack we are tracing is in the exception stack. This causes traces like: <idle>-0 [002] 34263.745825: raise_softirq_irqoff <-__blk_complete_request <idle>-0 [002] 34263.745826: <= 0 <= 0 <= 0 <= 0 <= 0 <= 0 <= 0 By returning "0" instead, the irq stack is saved as well, and we see: <idle>-0 [003] 883.280992: raise_softirq_irqoff <-__hrtimer_star t_range_ns <idle>-0 [003] 883.280992: <= hrtimer_start_range_ns <= tick_nohz_restart_sched_tick <= cpu_idle <= start_secondary <= <= 0 <= 0 [ Impact: record stacks from interrupts ] Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
