Or something like this. Ugly as hell, no question about that. I also
have to think about this some more to convince myself this will not
result in an endless loop under some situations.

Or something like this. Ugly as hell, no question about that. I also
have to think about this some more to convince myself this will not
result in an endless loop under some situations.

Baoquan He has noticed that 15c30bc09085 ("mm, memory_hotplug: make
has_unmovable_pages more robust") is causing memory offlining failures
on a movable node. After a further debugging it turned out that
has_unmovable_pages fails prematurely because it stumbles over off-LRU
