Subject: [PATCH 6/8] nilfs2: set up s_bdi like the generic mount_bdev code
Date: Tue, 30 Dec 2014 09:57:37 +0100 [thread overview]
Message-ID: <1419929859-24427-7-git-send-email-hch@lst.de> (raw)
In-Reply-To: <1419929859-24427-1-git-send-email-hch@lst.de>
mapping->backing_dev_info will go away, so don't rely on it.
