Pull SCSI target fixes from Nicholas Bellinger:

 "There has been work in a number of different areas over the last
  weeks, including:

   - Fix target-core-user (TCMU) back-end bi-directional handling (Xiubo
     Li + Mike Christie + Ilias Tsitsimpis)

   - Fix iscsi-target TMR reference leak during session shutdown (Rob
     Millner + Chu Yuan Lin)

   - Fix target_core_fabric_configfs.c race between LUN shutdown +
     mapped LUN creation (James Shen)

   - Fix target-core unknown fabric callback queue-full errors (Potnuri
     Bharat Teja)

   - Fix iscsi-target + iser-target queue-full handling in order to
     support iw_cxgb4 RNICs. (Potnuri Bharat Teja + Sagi Grimberg)

   - Fix ALUA transition state race between multiple initiator (Mike
     Christie)

   - Drop work-around for legacy GlobalSAN initiator, to allow QLogic
     57840S + 579xx offload HBAs to work out-of-the-box in MSFT
     environments. (Martin Svec + Arun Easi)

  Note that a number are CC'ed for stable, and although the queue-full
  bug-fixes required for iser-target to work with iw_cxgb4 aren't CC'ed
  here, they'll be posted to Greg-KH separately"
