Subject: [PATCH] [Target_Core_Mod 5/6]: Updates for generic device core
>>From 83f3b031993ef08fca5cffc9bc416ece901b538a Mon Sep 17 00:00:00 2001

Subject: [PATCH] [Target_Core_Mod]: Updates for generic device core
This patch adds a missing SCF_SE_LUN_CMD in __transport_get_lun_for_cmd()
Also, it adds a temporary NOP for transport_get_lun_for_tmr(), and adds
core_dec_lacl_count().
It also export the following symbols:
core_update_device_list_access()
core_dev_add_lun()
core_dev_del_lun()
core_get_lun_from_tpg()
core_dev_init_initiator_node_lun_acl()
core_dev_add_initiator_node_lun_acl()
core_dev_del_initiator_node_lun_acl()
