From 50ef37b96c11e76625067ae413dc54585ea22585 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Mon, 14 Apr 2008 18:52:05 +0300 Subject: [PATCH] slub: Fixes to per cpu stat output in sysfs Only output per cpu stats if the kernel is build for SMP. Use a capital "C" as a leading character for the processor number (same as the numa statistics that also use a capital letter "N").
