Right, that makes more sense. I also noticed that my patch will produce a compile error when CONFIG_NUMA is set but CONFIG_MIGRATION is not, because policy_zone is missing in that case. Since policy_zone is only used for NUMA, a better solution would be to use an "#ifdef CONFIG_NUMA" within vma_migratable(). I will send a new version of the patch.
Thanks, Gerald
