Let's use "PageOffline() + reference count = 0" as a sign to

has_unmovable_pages(). Use a new flag to indicate the
requirement of memory offlining to skip over these special pages.
In has_unmovable_pages(), make sure the pages won't be detected as
movable. This is not strictly necessary, however makes e.g.,

[PATCH RFC v3 0/9] virtio-mem: paravirtualized memory
Long time no RFC! I finally had time to get the next version of the Linux
driver side of virtio-mem into shape, incorporating ideas and feedback from

This RFC is based on the series currently on the mm list:
- [PATCH 0/3] Remove __online_page_set_limits()
- [PATCH v1 0/3] mm/memory_hotplug: Export generic_online_page()
- [PATCH v4 0/8] mm/memory_hotplug: Shrink zones before
