Subject: namespaces: exit_task_namespaces() invalidates nsproxy
From: Cedric Le Goater <clg@xxxxxxxxxx>
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.
