Subject: [PATCH 2/4] acpi,memory-hotplug : rename remove_memory() to offline_memory()
Date: Wed, 3 Oct 2012 19:02:45 +0900	[thread overview]
Message-ID: <506C0D45.3050909@jp.fujitsu.com> (raw)
In-Reply-To: <506C0AE8.40702@jp.fujitsu.com>

From: Yasuaki Ishimatsu <isimatu.yasuaki@jp.fujitsu.com>

add_memory() hot adds a physical memory. But remove_memory does not
hot remove a phsical memory. It only offlines memory. The name
confuse us.

So the patch renames remove_memory() to offline_memory(). We will
use rename_memory() for hot removing memory.
