kubernetes: HostPath mounts failing with "Path is not a shared or slave mount"

Is this a BUG REPORT or FEATURE REQUEST?: /kind bug

What happened: After upgrading from v1.9.2 -> v1.10.0-beta.2, containers using hostpath mounts are failing with:

        exitCode: 128
        finishedAt: 2018-03-12T19:25:03Z
        message: 'linux mounts: Path /opt/kubelet/dev is mounted on / but it is not
          a shared or slave mount.'
        reason: ContainerCannotRun
        startedAt: 2018-03-12T19:25:03Z

The message linux mounts: Path /opt/kubelet/dev is mounted on / but it is not a shared or slave mount seems like it’s from the docker daemon, but the docker daemon was not updated during the upgrade so I had assumed a behaviour in the kubelet had changed that would cause this.

What you expected to happen: Pod should be running as usual, but it fails with RunContainerError.

How to reproduce it (as minimally and precisely as possible): Run Kubernetes cluster using host path mount.
