Re: [RFC] mnt_already_visible(): should regular-file mountpoints participate in the visibility check?

Thanks to both of you for the replies.

@legion: The /proc/keys and /proc/interrupts case you raised is one
I missed, and it shows that a new mount can grant access that the
container's creators do not want to grant. I withdraw the suggestion.

@Brauner: you're right, and I apologize for the length. I'll keep
future questions to the bare minimum.

Thanks,
