Meaning that these calls end up doing nops? execve is always resetting unconditionally, there's no option to inherit the stats from the program running execve. By default all thread and mm stats are also resetted across fork/clone but there's a way to disable that with sysfs because those are more likely to retain some statistical significance. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
