[HPA stuff deleted]

Hi Bartlomiej,

Apart from HPA one also has DCO, which functions rather similarly.
(I have not checked whether the current kernel knows anything about DCO.)
Have you thought about DCO?
Probably the kernel should by default not touch any such setting.
Maybe it should be reported?
A user space utility might change this setting - thus a disk can change size.
