From 37c0708dbee5825df3bd9ce6ef2199c6c1713970 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Tue, 16 Oct 2007 01:25:36 -0700 Subject: Memoryless nodes: Add N_CPU node state We need the check for a node with cpu in zone reclaim. Zone reclaim will not allow remote zone reclaim if a node has a cpu.
