From 210a9ebef2d1bd32d9e9d81c84d538e237769cdb Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Tue, 9 Aug 2005 20:20:54 -0700 Subject: [NETFILTER]: ip{6}_queue: prevent unregistration race with nfnetlink_queue Since nfnetlink_queue can override ip{6}_queue as queue handlers, we can no longer blindly unregister whoever is registered for PF_INET[6], but only unregister ourselves.
