From: Miaohe Lin <linmiaohe@xxxxxxxxxx> Subject: mm/memory_hotplug: remove obsolete comment of __add_pages Patch series "A few cleanup patches around memory_hotplug". This series contains a few patches to fix obsolete and misplaced comments, clean up the try_offline_node function and so on. This patch (of 4): Since commit f1dd2cd13c4b ("mm, memory_hotplug: do not associate hotadded memory to zones until online"), there is no need to pass in the zone.
