    Pull overlayfs updates from Miklos Szeredi:
     "This fixes d_ino correctness in readdir, which brings overlayfs on par
      with normal filesystems regarding inode number semantics, as long as
      all layers are on the same filesystem.
    
      There are also some bug fixes, one in particular (random ioctl's
      shouldn't be able to modify lower layers) that touches some vfs code,
      but of course no-op for non-overlay fs"
