Yes, the more I read this code the more I think it is wrong. But sorry,
have no time to explain today. Will try tomorrow.

And yes, it seems that 2 simple fixes I sent makes sense in any case.
Even if we will (probably) need to change restore_shared_options() in
do_new_mount() later.

And cough... I can't resist ;) I understand that it is very easy to
blame the code which I do not understand even remotely, but imo
collect_mnt_namespaces() -> collect_mntns() paths ask for cleanups.
