[PATCH] namespaces: exit_task_namespaces() invalidates nsproxy
exit_task_namespaces() has replaced the former exit_namespace(). It invalidates task->nsproxy and associated namespaces. This is an issue for the (futur) pid namespace which is required to be valid in exit_notify(). This patch moves exit_task_namespaces() after exit_notify() to keep nsproxy valid.
