From: Julia Lawall <julia.law...@lip6.fr> 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. This seems to be a copy-paste bug from a previous debugging message, and so the meaningless value is just deleted.
This problem was found using Coccinelle (http://coccinelle.lip6.fr/).
