From: Adrian Hunter <adrian.hunter@xxxxxxxxx> commit d6bc34c5ec18c3544c4b0d85963768dfbcd24184 upstream. In __cmd_record(), when receiving SIGINT(ctrl + c), a 'done' flag will be set and the event list will be disabled by evlist__disable() once. While in auxtrace_record.read_finish(), the related events will be enabled again, if they are continuous, the recording seems to be endless. If the event is disabled, don't enable it again here.
