Subject: [PATCH v2 01/35] fs: introduce a ->s_cdev field into struct super_block
Date: Thu, 30 Jul 2015 13:47:57 +0800 [thread overview]
Message-ID: <1438235311-23788-2-git-send-email-yangds.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <1438235311-23788-1-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.
