Something like this would be shorter and visually much easier to parse: bash-3471 [003] 357.014755: [ MISS ] sched_info_dequeued:sched_stats.h:177 bash-3471 [003] 357.014756: [ .... ] update_curr:sched_fair.c:489 bash-3471 [003] 357.014758: [ .... ] calc_delta_fair:sched_fair.c:411 any objections against the patch below which implements this?
