Subject: [PATCH 3/6] [Target_Core_Mod/FILEIO): Update for EVPD and remove
legacy parameter code
>>From 984076ed2e111136e882b9aed68b0cd86b7c30ef Mon Sep 17 00:00:00 2001

Subject: [PATCH 3/6] [Target_Core_Mod/FILEIO): Update for EVPD and remove legacy parameter code
This patch removes FILEIO specific usage of lvm_uuid= and md_uuid= parameters
from legacy v2.9 code. Usage of this information including from 'lvs -v'
and 'mdadm -D /dev/mdX' can now be directly echoed into
/sys/kernel/config/target/core/$HBA/$STORAGE_OBJECT/wwn/evpd_unit_serial
