357 Variables allow data from one hist trigger to be saved by one hist
358 trigger and retrieved by another hist trigger. For example, a trigger
364 # echo 'hist:keys=pid:ts0=common_timestamp.usecs' >>
367 # echo 'hist:keys=next_pid:wakeup_lat=common_timestamp.usecs-$ts0' >>
371 as another type of hist_field and for a given hist trigger are added
593 each variable whenever a hist trigger is updated. Those resulting | |

696 When a hist trigger makes use of a variable, a new hist_field is

1622 the sched_switch trigger references a hist trigger field on another
