  [GIT PULL] overlayfs update for 4.7 Miklos Szeredi <miklos@szeredi.hu> - 2016-05-27 21:50 +0200

#1408258 — [GIT PULL] overlayfs update for 4.7

Hi Linus,

Please pull from:

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

The meat of this is a change to use the mounter's credentials for operations
that require elevated privileges (such as whiteout creation).  This fixes
behavior under user namespaces as well as being a nice cleanup.

Thanks,
Miklos
