Subject: [PATCH 14/19] jffs2: convert to ->shutdown_sb and ->free_sb
Date: Wed, 13 Sep 2023 08:10:08 -0300 [thread overview]
Message-ID: <20230913111013.77623-15-hch@lst.de> (raw)
In-Reply-To: <20230913111013.77623-1-hch@lst.de>
Convert jffs2 from ->kill_sb to ->shutdown_sb and ->free_sb. Drop
the otherwise unused kill_mtd_super helpers, as there is no benefit in
it over just calling put_mtd_device on sb->s_mtd.
Signed-off-by: Christoph Hellwig <hch@lst.de>
