Subject: [PATCH 7/9] target/iblock: fix holder printing in iblock_show_configfs_dev_params
Date: Thu, 3 Sep 2020 07:41:02 +0200 [thread overview]
Message-ID: <20200903054104.228829-8-hch@lst.de> (raw)
In-Reply-To: <20200903054104.228829-1-hch@lst.de>
bd_contains is never NULL for an open block device. In addition ibd_bd
is always set to a block device that was exclusively opened by the
target code, so the holder is guranteed to be ib_dev as well.
