[//]: # kind bug

Description

Trying to use bind-propagation shared with podman does not work.

Steps to reproduce the issue:

1. podman run --privileged -it --rm -v /root/owntmp:/owntmp:shared  fedora bash
2. [container] #  mount -o bind /usr /owntmp/usr
3. [container] #  ls /owntmp/usr
bin  games  include  lib  lib64  libexec  local  sbin  share  src  tmp
4. [host] # ls /root/owntmp/usr 

Describe the results you received:

An empty directory on the host.

Describe the results you expected:

A populated directory on the host. ls /root/owntmp/usr should give the same output as a ls /owntmp/usr in the container.
