Subject: [GIT PULL] overlayfs update for 4.9

Hi Al,

Please pull from:

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

This has an assortment of fixes and cleanups for overlayfs.

It also touches the VFS:

 - add the vfs_get_link() helper for calling i_op->get_link();
 - fix mnt_want_write_file() to freeze protect the underlying sb instead of
   overlay sb;
 - allow vfs_clone_file_range() to be called by overlayfs.

None of the above should have any effect on filesystems other than overlayfs.

Thanks,
Miklos
