FWIW, can't reproduce here - at least not with C reproducer +
-rc7^ kernel + .config from report + debian kvm image (bullseye,
with systemd shite replaced with sysvinit, which might be relevant).

In case systemd-specific braindamage is needed to reproduce it...
Hell knows; at least mount --make-rshared / doesn't seem to suffice.
