There has been a lot of other work this period but it is not quite ready yet, so I am pushing it until 4.5.

Security wise it is really a gimme as the user namespace root can already call setuid become that user and create the hardlink" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: namei: permit linking with CAP_FOWNER in userns
