Subject: [PATCH  6/21] inactive_anon_is_low-move-to-vmscan.patch
Date: Wed, 3 Dec 2008 13:54:31 +0900	[thread overview]
Message-ID: <20081203135431.a2acb02f.kamezawa.hiroyu@jp.fujitsu.com> (raw)
In-Reply-To: <20081203134718.6b60986f.kamezawa.hiroyu@jp.fujitsu.com>

The inactive_anon_is_low() is called only vmscan.
Then it can move to vmscan.c

This patch doesn't have any functional change.
