Subject: [PATCH 05/11] block: call blk_integrity_add earlier in device_add_disk
Date: Wed, 18 Aug 2021 16:45:36 +0200 [thread overview]
Message-ID: <20210818144542.19305-6-hch@lst.de> (raw)
In-Reply-To: <20210818144542.19305-1-hch@lst.de>
Doing all the sysfs file creation before adding the bdev and thus
allowing it to be opened will simplify the about to be added error
handling.
