Subject: [PATCH v3 4/4] mm/memory_hotplug: Drop node_online check in unregister_mem_sect_under_nodes
Date: Wed, 15 Aug 2018 16:42:19 +0200 [thread overview]
Message-ID: <20180815144219.6014-5-osalvador@techadventures.net> (raw)
In-Reply-To: <20180815144219.6014-1-osalvador@techadventures.net>
From: Oscar Salvador <osalvador@suse.de>
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.
