Date: Fri, 18 May 2012 02:03:39 +0900 From: Joonsoo Kim <js1304@...il.com> To: Pekka Enberg <penberg@...nel.org> Cc: Christoph Lameter <cl@...ux-foundation.org>, linux-kernel@...r.kernel.org, linux-mm@...ck.org, Joonsoo Kim <js1304@...il.com> Subject: [PATCH 1,2/4 v3] slub: use __cmpxchg_double_slab() at interrupt disabled place get_freelist(), unfreeze_partials() are only called with interrupt disabled, so __cmpxchg_double_slab() is suitable.
