...PageOffline() and result in issues if offlining fails and the pages are suddenly in the buddy). Let's use "PageOffline() + reference count = 0" as a sign to memory offlining code that these pages can simply be skipped when offlining, similar to free or HWPoison pages. Pass flags to test_pages_isolated(), similar as already done for 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., alloc_conti...

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 previous discussions. 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
