[GIT PULL] target fixes for v4.2-rc5

[Nicholas A. Bellinger]

Hi Linus,

Here are the outstanding target-pending fixes for v4.2-rc5 code.

Please go ahead and pull from:

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

This series is larger than what I'd normally be conformable with sending
for a -rc5 PULL request..

However, the bulk of the series is localized to qla2xxx target specific
fixes that address a number of real-world correctness issues, that have
been outstanding on the list for ~6 weeks now.  They where submitted +
verified + acked by the HW LLD vendor, contributed by a major production
customer of the code, and are marked for v3.18.y stable code.

That said, I don't see a good reason to wait another month to get these
fixes into mainline.

Beyond the qla2xx specific fixes, this series also includes:

  - Bugfix for a long standing use-after-free in iscsi-target during
    TPG shutdown + demo-mode sessions.
  - Bugfix for a >= v4.0 regression OOPs in iscsi-target during a
    iscsi_start_kthreads() failure.
  - Bugfix for a >= v4.0 regression hang in iscsi-target for iser
    explicit session/connection logout.
  - Bugfix for a iser-target bug where a early CMA REJECTED status
    during login triggers a NULL pointer dereference OOPs.
  - Bugfixes for a handful of v4.2-rc1 specific regressions related
    to the larger set of recent backend configfs attribute changes.

A big thanks to QLogic + Pure Storage for the qla2xxx target bugfixes.

Thank you,
