  "message": "x86/stacktrace: return 0 instead of -1 for stack ops\n\nIf we return -1 in the ops-\u003estack for the stacktrace saving, we end up\nbreaking out of the loop if the stack we are tracing is in the exception\nstack. This causes traces like:\n\n          \u003cidle\u003e-0     [002] 34263.745825: raise_softirq_irqoff \u003c-__blk_complete_request\n          \u003cidle\u003e-0     [002] 34263.745826:\n \u003c\u003d 0\n \u003c\u003d 0\n \u003c\u003d 0\n \u003c\u003d 0\n \u003c\u003d 0\n \u003c\u003d 0\n \u003c\u003d 0\n\nBy returning \"0\" instead, the irq stack is saved as well, and we see:\n\n          \u003cidle\u003e-0     [003]   883.280992: raise_softirq_irqoff \u003c-__hrtimer_star\nt_range_ns\n          \u003cidle\u003e-0     [003]   883.280992:\n \u003c\u003d hrtimer_start_range_ns\n \u003c\u003d tick_nohz_restart_sched_tick\n \u003c\u003d cpu_idle\n \u003c\u003d start_secondary\n \u003c\u003d\n \u003c\u003d 0\n \u003c\u003d 0\n\n[ Impact: record stacks from interrupts ]\n\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n",
