The original format for sched_stat_iowait and sched_stat_sleep:
$ cat events/sched/sched_stat_iowait/format
...
print fmt: "comm=%s pid=%d delay=%Lu [ns]", ...
$ cat events/sched/sched_stat_sleep/format
...
print fmt: "comm=%s pid=%d delay=%Lu [ns]", ...
But commit commit 75ec29ab84
("tracing: Convert some sched trace events to DEFINE_EVENT and
_PRINT") broke the format:
$ cat events/sched/sched_stat_iowait/format
print fmt: "task: %s:%d iowait: %Lu [ns]", ...
$ cat events/sched/sched_stat_sleep/format
print fmt: "task: %s:%d sleep: %Lu [ns]", ...
No change in functionality.
