Humm, I see that there is currently no way to just "undup" a bug. It's possible to remark it as invalid, or fix with commits, but not possible to just undup and get into "open" state. I've filed https://github.com/google/syzkaller/issues/520 for this. Meanwhile, please add either Reported-by: tag from the other bug, or from both. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
