Subject: [PATCH 2/2] autofs: use IS_ROOT to replace root dentry checks
Date: Tue, 03 Dec 2013 13:11:42 +0800 [thread overview]
Message-ID: <20131203051141.15048.50495.stgit@perseus.fritz.box> (raw)
In-Reply-To: <20131203050323.15048.52933.stgit@perseus.fritz.box>
From: Rui Xiang <rui.xiang@huawei.com>
Use the helper macro !IS_ROOT to replace parent != dentry->d_parent.
Just clean up.
