From 804d5dd348567fd286b8aa5101d3aff95ecd69d7 Mon Sep 17 00:00:00 2001 From: Pekka Paalanen Date: Wed, 9 Nov 2011 16:27:07 +0200 Subject: [PATCH] util: clear pointers on wl_list_remove() Set the next and prev pointers of the removed list element to NULL. This will catch programming errors that would use invalid list pointers, double-remove for instance. It also helps debugging, making it easy to see in gdb if an object is not in a list.
