Well. I don't understand your use-case. Or any other use-case for drivers/connector/ that I know nothing about. But this is irrelevant. The new PROC_CN_MCAST_NOTIFY functionality you propose should work regardless of whether this task is ptraced or not. But it doesn't because the usage of ->exit_code in your patch conflicts with the current usage of this field. So, NACK, sorry. Oleg.
