Subject: [PATCH 5/6] scsi: use 64-bit value for 'max_luns'
Date: Sat, 31 May 2014 11:01:17 +0200 [thread overview]
Message-ID: <1401526878-119472-6-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1401526878-119472-1-git-send-email-hare@suse.de>
Now that we're using 64-bit LUNs internally we need to increase
the size of max_luns to 64 bits, too.
