Hi Andrew, Minchan, and all: My former patch "HWPOISON: soft offlining for non-lru movable page" will cause compiled error when disable CONFIG_MIGRATION. And this is a patch to fixe it by define isolate_movable_page as a static inline function with !CONFIG_MIGRATION.
Could you please help to review it ? Thanks so much~ I am so sorry about that. Thanks.
