When an event is disabled the "tracking" events selected by the 'mmap', 'comm' and 'task' bits of struct perf_event_attr, are also disabled. However, the information those events provide is necessary to resolve symbols for when the main event is re-enabled. The "tracking" events can be kept enabled by putting them on another event, but that requires an event that otherwise does nothing. A new software event PERF_COUNT_SW_DUMMY is added for that purpose.
