From ebe29738f3934ad6a93c8bd76e30aa5d797a269d Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Wed, 6 Dec 2006 20:32:59 -0800 Subject: [PATCH] [PATCH] Remove uses of kmem_cache_t from mm/* and include/linux/slab.h Remove all uses of kmem_cache_t (the most were left in slab.h). The typedef for kmem_cache_t is then only necessary for other kernel subsystems. Add a comment to that effect.
