From 068ce415bea9e2b96bde76dc1bf6e672a89903ee Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 8 Jul 2012 13:37:40 +0200 Subject: [PATCH] slub: remove invalid reference to list iterator variable If list_for_each_entry, etc complete a traversal of the list, the iterator variable ends up pointing to an address at an offset from the list head, and not a meaningful structure. Thus this value should not be used after the end of the iterator. The patch replaces s->name by al->name, which is referenced nearby. This problem was found using Coccinelle (http://coccinelle.lip6.fr/).
