Subject: [PATCH 2/7] dcssblk: don't set bd_block_size in ->open
Date: Fri, 26 Jun 2020 10:01:53 +0200
Message-ID: <20200626080158.1998621-3-hch@lst.de> (raw)
In-Reply-To: <20200626080158.1998621-1-hch@lst.de>

bd_block_size contains a value that matches the logic block size when
opening, so the statement is redundant.  Even if it wasn't the dumb
assignment would cause a a mismatch with bd_inode->i_blkbits.
