Subject: [PATCH 3/2][BUGFIX] fix memory isolation notifier return value check
Date: Fri, 3 Sep 2010 16:57:13 +0900	[thread overview]
Message-ID: <20100903165713.88249349.kamezawa.hiroyu@jp.fujitsu.com> (raw)
In-Reply-To: <20100903121003.e2b8993a.kamezawa.hiroyu@jp.fujitsu.com>

Sorry, the 3rd patch for this set.
==

From: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com>

Even if notifier cannot find any pages, it doesn't mean
no pages are available...(For example, there is no notifier.)
Anyway, we check all pages in the range, later.
