OverlayFS was introduced in https://git.kernel.org/linus/e9be9d (v3.18-rc2)
So it don't affects any kernel < 3.18.
Debian stable has 3.16

Not to mention that debian requires you to explicitly enable the kernel.unprivileged_userns_clone sysctl for non-privileged user namespace support, and the fact that even then you can't mount overlayfs (see erics comment above).
