[GIT PULL] target fixes for v4.11-rc7

[Nicholas A. Bellinger]

Hi Linus,

Here are the outstanding target-pending bug-fixes for v4.11-rc7.

Please go ahead and pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git master

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.

Thank you,
