> Signed-off-by: Wei Yang <richard.weiyang@xxxxxxxxx> Good catch. One thing I was wondering is that if we also should re-adjust it when a zone gets emptied during offlining memory. I checked, and whenever we work wirh pgdat->nr_zones we seem to check if the zone is populated in order to work with it. But still, I wonder if we should re-adjust it.
