I guess we are both talking about the same thing in different words. All the allocations are static before the patch while all are dynamic after the patch.

This will depend on the particular configuration but it will at least give a picture what the savings might be. -- Michal Hocko SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
