    To reproduce this bug the file must be in an OverlayFS mount
Reproduced on:

linux-image-4.4.0-159-generic/xenial-updates,xenial-security,now 4.4.0-159.187 amd64
linux-image-4.4.0-165-generic/xenial-updates,xenial-security,now 4.4.0-165.193 amd64

Install packages libacl1-dev, build-essential, and gcc.
Included is a C program that reproduces the bug and two scripts. Run them in order.

make-overlay.sh: creates directories in /tmp and mounts /tmp/overlay as an overlay filesystem
