Hi. Same problem here. Some partitions still appear in `mount` output and `/proc/mounts` but can't be unmounted via either device name or mount point. Repeatedly trying `umount -l` with device names and mount points finally managed to get the partitions unmounted.
Yet it feels awkward, like a worn out door lock that locks okay but you have to shake for a while to have it unlock.

When you mount with --rbind, umount should be able to reverse the process, unmounting all recursively bound mounts.
