Comment 24 for bug 1857257

It seems like the patch you committed to fix this bug causes the overlay module to crash on one of my Ubuntu 18.04 machines.

When using linux-generic 5.3.0-52.46, as soon as my gitlab-runner tries to start up a Docker container, dmesg spits out the stuff you can see in the "dmesg-excerpt.txt" attachment.

Downgrading to linux-generic 5.3.0-51.44 solves the issue. I haven't bisected this, but looking at the git commit history, your patch looks like the obvious culprit to me.
