Message-Id: <20180508180436.716-76-mfasheh@suse.de>
Date: Tue, 8 May 2018 11:04:35 -0700
From: Mark Fasheh <mfasheh@...e.de>
To: linux-fsdevel@...r.kernel.org
Cc: linux-kernel@...r.kernel.org, linux-btrfs@...r.kernel.org,
Mark Fasheh <mfasheh@...e.de>
Subject: [PATCH 75/76] fs: Use fs view device from struct super_block
We have some places which access s_dev directly from struct super_block.
Convert those to get v_dev from the default super block view.
Signed-off-by: Mark Fasheh <mfasheh@...e.de>
