The subsection capability is strictly limited to arch_add_memory() users that never online the memory, i.e. only ZONE_DEVICE / devm_memremap_pages() users. So this isn't "memory-hotplug" as much as it is "support for subsection vmemmap management". > Documentation/vm/memory-model.rst This looks more fitting and should probably include a paragraph on the general ZONE_DEVICE / devm_memremap_pages() use case.
