From 6047a007d0f6b7395cd158f3bdda34ab39a48821 Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Wed, 14 Jan 2009 12:22:25 +0200 Subject: [PATCH] SLUB: Use ->objsize from struct kmem_cache_cpu in slab_free() There's no reason to use ->objsize from struct kmem_cache in slab_free() for the SLAB_DEBUG_OBJECTS case. All it does is generate extra cache pressure as we try very hard not to touch struct kmem_cache in the fast-path.
