From 2b6bf15f464620bbee08e8257d11f8f9f7f8725f Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Tue, 22 Mar 2022 14:47:16 -0700 Subject: [PATCH] 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.
