The event_limit can be set by the PERF_EVENT_IOC_REFRESH to limit the number of events. When the event_limit reaches 0, the POLL_HUP signal should be sent. But it's missed. The corresponding counter should be stopped when the event_limit reaches 0. It was implemented in the ARCH-specific code. However, since the commit9734e25fbf("perf: Fix the throttle logic for a group"), all the ARCH-specific code has been moved to the generic code. The code to handle the event_limit was lost. Add the event->pmu->stop(event, 0); back.
