From e35e1a9744bfc267bf511c2f37266103994466c8 Mon Sep 17 00:00:00 2001 From: Chen Gang Date: Fri, 12 Jul 2013 08:23:48 +0800 Subject: [PATCH] mm/slub: remove 'per_cpu' which is useless variable Remove 'per_cpu', since it is useless now after the patch: "205ab99 slub: Update statistics handling for variable order slabs". And the partial list is handled in the same way as the per cpu slab.
