Hello Michal,
I've read a recent discussion about introducing the memory types for
memory hotplug:
https://marc.info/?t=153814716600004&r=1&w=2
In particular I was interested in the idea of moving vmem struct pages
to the hotplugable memory itself. I'm also looking into it for s390
right now. So, in one of your replies you mentioned that you "have
proposed (but haven't finished this due to other stuff) a solution for
this". Have you covered any part of that solution yet? Could you please
point me to any relevant discussions on this matter?
Thanks,
Mikhail Zaslonko
