Subject: [PATCH 4/4] ext4: fix a wrong comment in __mb_check_buddy
Date: Thu, 15 Sep 2011 15:09:40 +0800	[thread overview]
Message-ID: <1316070580-10723-4-git-send-email-hao.bigrat@gmail.com> (raw)
In-Reply-To: <1316070580-10723-1-git-send-email-hao.bigrat@gmail.com>

From: Robin Dong <sanbai@taobao.com>

The comment says the bit should be 0, but the after code assert the bit to be 1.
This makes people confused, so fix it.
