From adf653f92f38e80a78bb77e912d49bcc8055330f Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 25 May 2015 21:33:08 -0700 Subject: target: Subsume se_port + t10_alua_tg_pt_gp_member into se_lun This patch eliminates all se_port + t10_alua_tg_pt_gp_member usage, and converts current users to direct se_lun pointer dereference. This includes the removal of core_export_port(), core_release_port() core_dev_export() and core_dev_unexport(). Along with conversion of special case se_lun pointer dereference within PR ALL_TG_PT=1 and ALUA access state transition UNIT_ATTENTION handling. Also, update core_enable_device_list_for_node() to reference the new per se_lun->lun_deve_list when creating a new entry, or replacing an existing one via RCU.
