The patch titled
identifier to nsproxy
has been removed from the -mm tree. Its filename was

------------------------------------------------------
Subject: identifier to nsproxy
From: Cedric Le Goater <clg@xxxxxxxxxx>
Add an identifier to nsproxy. The default init_ns_proxy has identifier 0 and
allocated nsproxies are given -1.
This identifier will be used by a new syscall sys_bind_ns.
