Subject: [PATCH v3 01/39] fs: introduce a ->s_cdev field into struct super_block
Date: Tue, 15 Sep 2015 17:01:56 +0800 [thread overview]
Message-ID: <1442307754-13233-2-git-send-email-yangds.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <1442307754-13233-1-git-send-email-yangds.fnst@cn.fujitsu.com>
There are some filesystems are running on char devs, such
as ubifs. So we need a field in super_block to hold a
reference to the char device.
