From 5bb983b0cce9b7b281af15730f7019116dd42568 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Thu, 7 Feb 2008 17:47:41 -0800 Subject: [PATCH] SLUB: Deal with annoying gcc warning on kfree() gcc 4.2 spits out an annoying warning if one casts a const void * pointer to a void * pointer. No warning is generated if the conversion is done through an assignment.
