pool is complex. As the bz points out an extended partition should have

adjust the allocation of the extended partition.

partition was deleted; however, since we now have special logic to handle

backend-agnostic, so the backend is not used if there is no specific
pagesize of hugepages requested, no nodeset the memory node should be
bound to, no memory access change required, and so on.
So since the introduction of the memory-backend-file object until now we
