What's the reason for not enabling this by > default? Performance regressions? I'm worried about performance regressions because this patch checks a stack overflow in detail.

So, I'd like to send the revised patch if it does not have any further problem. > Pekka > > -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
