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"). Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi>
