For a while we need to have a dummy event for doing things like receiving PERF_RECORD_COMM, PERF_RECORD_EXEC, etc for threads being created and dying while we synthesize the pre-existing ones at tool start. This 'dummy' event is needed for keeping track of thread lifetime events early in the session but are uninteresting otherwise, i.e. no need to have it in a initial events menu for the non-grouped case, i.e. for: # perf top -e cycles,instructions or even for plain: # perf top When 'cycles' and that 'dummy' event are in place. The code to remove that 'dummy' event ended up creating an endless loop for the grouped case, i.e.: # perf top -e '{cycles,instructions}' Fix it.
