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.
[akpm@xxxxxxxxxxxxxxxxxxxx: remove the comment altogether, per David]
