[PATCH v2 fixed 06/16] exec: Reuse qemu_ram_apply_settings() in qemu_ram_remap()
Posted by David Hildenbrand 5 years, 9 months ago
I don't see why we shouldn't apply all settings to make it look like the
surrounding RAM (and enable proper VMA merging).

Note: memory backend settings might have overridden these settings. We
would need a callback to let the memory backend fix that up.
