The patch titled
Memoryless nodes: SLUB support
has been removed from the -mm tree. Its filename was
memoryless-nodes-slub-support.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Memoryless nodes: SLUB support
From: Christoph Lameter <clameter@xxxxxxx>
Simply switch all for_each_online_node to for_each_node_state(NORMAL_MEMORY).
That way SLUB only operates on nodes with regular memory. Any allocation
attempt on a memoryless node or a node with just highmem will fall whereupon
SLUB will fetch memory from a nearby node (depending on how memory policies
and cpuset describe fallback).
