From 8ab1372fac5684de56c68f0da1ddc90e1c4ce740 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Tue, 17 Jul 2007 04:03:32 -0700 Subject: [PATCH] SLUB: Fix CONFIG_SLUB_DEBUG use for CONFIG_NUMA We currently cannot disable CONFIG_SLUB_DEBUG for CONFIG_NUMA. Now that embedded systems start to use NUMA we may need this. Put an #ifdef around places where NUMA only code uses fields only valid for CONFIG_SLUB_DEBUG.
