Jiri Olsa 179033b3e0 perf: Add PERF_EVENT_STATE_EXIT state for events with exited task ... Adding new perf event state to indicate that the monitored task has exited. In this case the event stays alive until the owner task exits or close the event fd while providing the last data through the read syscall and ring buffer. Instead it needs to propagate the error info (monitored task has died) via poll and read syscalls by returning POLLHUP and 0 respectively.
