At least for Opterons and other small NUMAs I have my doubts this is a good strategy. However it probably shouldn't happen very often, but if it happened it would be the wrong thing. In general shouldn't there be a printk at least? Doing such things silently is a bit nasty. -Andi -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
