From e24805637d2d270d7975502e9024d473de86afdb Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Sat, 4 Oct 2014 04:23:15 +0000 Subject: target: Fix APTPL metadata handling for dynamic MappedLUNs This patch fixes a bug in handling of SPC-3 PR Activate Persistence across Target Power Loss (APTPL) logic where re-creation of state for MappedLUNs from dynamically generated NodeACLs did not occur during I_T Nexus establishment. It adds the missing core_scsi3_check_aptpl_registration() call during core_tpg_check_initiator_node_acl() -> core_tpg_add_node_to_devs() in order to replay any pre-loaded APTPL metadata state associated with the newly connected SCSI Initiator Port.
