Note: I seem to get an error when I try to build this with kernel versions 4.12+. See Bug report on Github for details.
Also note that this version is not working with the lts kernel package (linux-lts).
I recommend using the lts version instead, see shiftfs-lts-dkms.
You will get a kernel panic if you try to mount an overlayfs on top of a shiftfs without an additional kernel patch. See my comment on shiftfs-dkms.
shiftfs is a kernel filesystem for uid/gid-shifting.
It is used by LXD for example.
More Details (including limitations etc.) in the official LXD forum:
https://discuss.linuxcontainers.org/t/trying-out-shiftfs/5155
https://discuss.linuxcontainers.org/t/lxd-usecases-of-shiftfs-volume-disk-share/7735
Report on the initial implementation in the Ubuntu Kernel repo:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1823186
If you use the LXD package from the Arch Repos, shiftfs will be enabled by default. You can check whether it is enabled with "lxc info" (look for: shiftfs: "true").
