    Pull target updates from Nicholas Bellinger:
     "It has been a very busy development cycle this time around in target
      land, with the highlights including:
    
       - Kill struct se_subsystem_dev, in favor of direct se_device usage
         (hch)
       - Simplify reservations code by combining SPC-3 + SCSI-2 support for
         virtual backends only (hch)
       - Simplify ALUA code for virtual only backends, and remove left over
         abstractions (hch)
       - Pass sense_reason_t as return value for I/O submission path (hch)
       - Refactor MODE_SENSE emulation to allow for easier addition of new
         mode pages.  (roland)
       - Add emulation of MODE_SELECT (roland)
       - Fix bug in handling of ExpStatSN wrap-around (steve)
       - Fix bug in TMR ABORT_TASK lookup in qla2xxx target (steve)
       - Add WRITE_SAME w/ UNMAP=0 support for IBLOCK backends (nab)
       - Convert ib_srpt to use modern target_submit_cmd caller + drop
         legacy ioctx->kref usage (nab)
       - Convert ib_srpt to use modern target_submit_tmr caller (nab)
       - Add link_magic for fabric allow_link destination target_items for
         symlinks within target_core_fabric_configfs.c code (nab)
       - Allocate pointers in instead of full structs for
         config_group->default_groups (sebastian)
       - Fix 32-bit highmem breakage for FILEIO (sebastian)
    
      All told, hch was able to shave off another ~1K LOC by killing the
      se_subsystem_dev abstraction, along with a number of PR + ALUA
      simplifications.  Also, a nice patch by Roland is the refactoring of
      MODE_SENSE handling, along with the addition of initial MODE_SELECT
      emulation support for virtual backends.
    
      Sebastian found a long-standing issue wrt to allocation of full
      config_group instead of pointers for config_group->default_group[]
      setup in a number of areas, which ends up saving memory with big
      configurations.  He also managed to fix another long-standing BUG wrt
      to broken 32-bit highmem support within the FILEIO backend driver.
    
      Thank you again to everyone who contributed this round!"
