Subject: [PART2 Patch] node: cleanup node_state_attr
Date: Wed, 31 Oct 2012 14:55:28 +0800	[thread overview]
Message-ID: <1351666528-8226-2-git-send-email-wency@cn.fujitsu.com> (raw)
In-Reply-To: <1351666528-8226-1-git-send-email-wency@cn.fujitsu.com>

From: Lai Jiangshan <laijs@cn.fujitsu.com>

use [index] = init_value
use N_xxxxx instead of hardcode.

Make it more readability and easier to add new state.
