From a7479d74460a4873b73534aa89cb82ab70ff8a32 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Thu, 16 Aug 2012 21:12:38 -0600 Subject: [PATCH] PCI: Leave normal LIST_POISON in deleted list entries list_del() already sets next/prev to LIST_POISON1/LIST_POISON2, so we don't need to do anything special here to prevent further list accesses.
