I am fully aware of this.
This is why we have /proc/vm/treat_hugepages_as_moveable which I did set.
Did you remove this option?

I don't need/have memory hotplug so I am ok with huge pages beeing not
movable in the movable zone.
The idea here is that other pages in that zone should be moveable so I
should be able to move all of them outside and replace them with hugepages.
This clearly doesn't work here so thats why I am asking my question

Best regards,
    Maxim Levitsky
