From 9cb78c16f5dadefd8dc5ba0ae5a2f26cd59419b3 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Wed, 25 Jun 2014 15:27:36 +0200 Subject: scsi: use 64-bit LUNs The SCSI standard defines 64-bit values for LUNs, and large arrays employing large or hierarchical LUN numbers become more and more common. So update the linux SCSI stack to use 64-bit LUN numbers.
