Subject: [RFC PATCH v3 04/31] memory_hotplug: export ensure_zone_is_initialized() in mm/internal.h
Date: Thu,  2 May 2013 17:00:36 -0700	[thread overview]
Message-ID: <1367539263-19999-5-git-send-email-cody@linux.vnet.ibm.com> (raw)
In-Reply-To: <1367539263-19999-1-git-send-email-cody@linux.vnet.ibm.com>

Export ensure_zone_is_initialized() so that it can be used to initialize
new zones within the dynamic numa code.
