From 8f4c765c22deee766319ae9a1db68325f14816e6 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Wed, 5 Sep 2012 00:18:32 +0000 Subject: mm/sl[aou]b: Move freeing of kmem_cache structure to common code The freeing action is basically the same in all slab allocators. Move to the common kmem_cache_destroy() function.
