This patch adds the TCM_Loop Linux/SCSI LLD fabric module for accessing TCM device backstores as locally accessable SCSI LUNs in virtual SAS, FC, and iSCSI Target ports using the generic fabric TransportID and Target Port WWN naming handlers from TCM's target_core_fabric_lib.c The TCM_Loop module uses the generic fabric configfs infratructure provided by target_core_fabric_configfs.c and adds a module dependent attribute for the creation/release of the virtual I_T Nexus connected the TCM_Loop Target and Initiator Ports. TCM_Loop can also be used with scsi-generic and BSG drivers so that STGT userspace fabric modules, QEMU-KVM and other hypervisor SCSI passthrough support can access TCM device backstore and control CDB emulation.
