From cbb79694d592e9a76880f6ef6db8feccaeee1c32 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Wed, 5 Sep 2012 00:18:32 +0000 Subject: mm/sl[aou]b: Do slab aliasing call from common code The slab aliasing logic causes some strange contortions in slub. So add a call to deal with aliases to slab_common.c but disable it for other slab allocators by providng stubs that fail to create aliases. Full general support for aliases will require additional cleanup passes and more standardization of fields in kmem_cache.
