When running event-no-pid test on small machines (e.g. cloud 1-core
instance), other events might not happen:
+ cat trace
+ cnt=0
+ [ 0 -eq 0 ]
+ fail No other events were recorded
[15] event tracing - restricts events based on pid notrace filtering [FAIL]
Schedule a simple sleep task to be sure that some other process events
get recorded.
