There are two conflicting formats described in this document:
1) prev_comm=kcompactd0 prev_pid=21 prev_prio=120 prev_state=S ==> next_comm=rcu_preempt next_pid=13 next_prio=120
2) task kcompactd0:21 [120] (S) ==> rcu_preempt:13 [120]
The second one appears to be wrong. It is not what you will see when you read '/sys/kernel/debug/tracing/events/sched/sched_switch/format'.
