Subject: [PATCH 3/4] ocfs2: stop using bdev->bd_super for journal error logging
Date:   Mon,  7 Aug 2023 12:26:24 +0100
Message-Id: <20230807112625.652089-4-hch@lst.de>
In-Reply-To: <20230807112625.652089-1-hch@lst.de>

All ocfs2 journal error handling and logging is based on buffer_heads,
and the owning inode and thus super_block can be retrieved through
bh->b_assoc_map->host.  Switch to using that to remove the last users
of bdev->bd_super.
