Subject: [PATCH v3 8/8] nvmet: use NVME_IDENTIFY_DATA_SIZE
Date: Fri,  2 Jun 2017 11:45:36 +0200	[thread overview]
Message-ID: <20170602094536.25775-9-jthumshirn@suse.de> (raw)
In-Reply-To: <20170602094536.25775-1-jthumshirn@suse.de>

Use NVME_IDENTIFY_DATA_SIZE define instead of hard coding the magic
4096 value.
