    Pull SCSI target updates from Nicholas Bellinger:
     "It's been a busy development cycle for target-core in a number of
      different areas.
    
      The fabric API usage for se_node_acl allocation is now within
      target-core code, dropping the external API callers for all fabric
      drivers tree-wide.
    
      There is a new conversion to RCU hlists for se_node_acl and
      se_portal_group LUN mappings, that turns fast-past LUN lookup into a
      completely lockless code-path.  It also removes the original
      hard-coded limitation of 256 LUNs per fabric endpoint.
    
      The configfs attributes for backends can now be shared between core
      and driver code, allowing existing drivers to use common code while
      still allowing flexibility for new backend provided attributes.
    
      The highlights include:
    
       - Merge sbc_verify_dif_* into common code (sagi)
       - Remove iscsi-target support for obsolete IFMarker/OFMarker
         (Christophe Vu-Brugier)
       - Add bidi support in target/user backend (ilias + vangelis + agover)
       - Move se_node_acl allocation into target-core code (hch)
       - Add crc_t10dif_update common helper (akinobu + mkp)
       - Handle target-core odd SGL mapping for data transfer memory
         (akinobu)
       - Move transport ID handling into target-core (hch)
       - Move task tag into struct se_cmd + support 64-bit tags (bart)
       - Convert se_node_acl->device_list[] to RCU hlist (nab + hch +
         paulmck)
       - Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch +
         paulmck)
       - Simplify target backend driver registration (hch)
       - Consolidate + simplify target backend attribute implementations
         (hch + nab)
       - Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch)
       - Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab)
       - Drop unnecessary core_tpg_register TFO parameter (nab)
       - Use 64-bit LUNs tree-wide (hannes)
       - Drop left-over TARGET_MAX_LUNS_PER_TRANSPORT limit (hannes)"
