Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm...

Pull userns hardlink capability check fix from Eric Biederman:
 "This round just contains a single patch.  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.

  The remaining change by Dirk Steinmetz wich fixes both Gentoo and
  Ubuntu containers allows hardlinks if we have the appropriate
  capabilities in the user namespace.  Security wise it is really a
  gimme as the user namespace root can already call setuid become that
  user and create the hardlink"
