[PATCH v4 4/4] mm/memory_hotplug: Drop node_online check in unregister_mem_sect_under_nodes
From: Oscar Salvador
Date: Fri Aug 17 2018 - 05:00:40 EST
From: Oscar Salvador <osalvador@xxxxxxx>
We are getting the nid from the pages that are not yet removed,
but a node can only be offline when its memory/cpu's have been removed.
Therefore, we know that the node is still online.
