Subject: [RFC PATCH v3 1/13] memory-hotplug : rename remove_memory to offline_memory
Date: Mon, 9 Jul 2012 19:23:11 +0900	[thread overview]
Message-ID: <4FFAB10F.9070701@jp.fujitsu.com> (raw)
In-Reply-To: <4FFAB0A2.8070304@jp.fujitsu.com>

remove_memory() does not remove memory but just offlines memory. The patch
changes name of it to offline_memory().
