Subject: [GIT PULL] overlayfs fixes for 4.9-rc3

Hi Linus,

Please pull from:

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

Fix two more POSIX ACL bugs introduced in 4.8 and add a missing fsync during
copy up to prevent possible data loss.

Also introduce the concept of feature flags to allow backward incompatible
changes to the overlay format.  This should have been there from day one; the
best we can do now is backport to stable kernels.  Add the check for features
without adding any actual features yet.

Thanks,
Miklos
