Hi, This patch set is used to support multiple target nodes demotion if a system has multiple slow memory nodes. Please help to review. Thanks. Changes from v1: - Add a new patch to allocate the node_demotion dynamically. - Update some comments. - Simplify some variables' name. Changes from RFC v2: - Change to 'short' type for target nodes array. - Remove nodemask instead selecting target node directly. - Add WARN_ONCE() if the target nodes exceed the maximum value. Changes from RFC v1: - Re-define the node_demotion structure. - Set up multiple target nodes by validating the node distance. - Add more comments.
