Subject: Memoryless nodes: SLUB support
From: Lee Schermerhorn <lee.schermerhorn@xxxxxx>
Memoryless nodes: SLUB support
Simply switch all for_each_online_node to for_each_memory_node. That way SLUB
only operates on nodes with memory. Any allocation attempt on a memoryless
node will fall whereupon SLUB will fetch memory from a nearby node (depending
on how memory policies and cpuset describe fallback).
