From 0cb992eda1f7e7672775032378690baa87c0e13d Mon Sep 17 00:00:00 2001 From: Wayne Boyer Date: Thu, 4 Nov 2010 09:35:58 -0700 Subject: [PATCH] [SCSI] ipr: fix lun assignment and comparison The lun value was not getting set up correctly for all devices attached to the new 64 bit adapters. The fix is to move the logic to earlier in the ipr_init_res_entry routine such that the value does get set correctly for all devices. Then the ipr_is_same_device comparison function was using the wrong lun value in the logic for the new adapters. Change this to use the correct lun value.
