Subject: [PATCH 19/25] nilfs2: Convert to properly refcounting bdi
Date: Wed, 29 Mar 2017 12:56:17 +0200	[thread overview]
Message-ID: <20170329105623.18241-20-jack@suse.cz> (raw)
In-Reply-To: <20170329105623.18241-1-jack@suse.cz>

Similarly to set_bdev_super() NILFS2 just used block device reference to
bdi. Convert it to properly getting bdi reference. The reference will
get automatically dropped on superblock destruction.
