[GIT PULL] overlayfs fixes for 4.7-rc3

[Miklos Szeredi]

Hi Linus,

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git overlayfs-linus

This contains two regression fixes: one for the xattr API update and one for
using the mounter's creds in file creation in overlayfs.  There's also a fix for
a bug in handling hard linked AF_UNIX sockets that's been there from day one.
This fix is overlayfs only despite the fact that it touches code outside the
overlay filesystem: d_real() is an identity function for all except overlay
dentries.

Thanks,
Miklos
