In all seriousness I do agree with you on these Keith in the long term. We
would consider adding property flags for the memory as it is added to the p2p
core and then the allocator could evolve to intelligently dish it out.
Attributes like endurance, latency and special write commit requirements could
all become attributes in time. Perhaps one more reason for a central entity for
p2p memory allocation so this code does not end up having to go into many
different drivers?
Ugh, I don't know... An allocator for PMR is going to be quite a
different animal. It would probably need to look more like a filesystem
given you'd need to access the same regions across reboots. I don't
think it fits the p2pmem paradigm at all. I think it's something
entirely new all together and who knows exactly what it will look like.
