[GIT PULL] target fixes for v4.2-rc7

[Nicholas A. Bellinger]

Hi Linus,

Here are the outstanding target-pending fixes for v4.2-rc7 code.

Please pull from:

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

It contains a v4.2-rc specific RCU module unload regression bug-fix, a
long-standing iscsi-target bug-fix for duplicate target_xfer_tags during
NOP processing from Alexei, and two more small REPORT_LUNs emulation
related patches to make Solaris FC host LUN scanning happy from Roland.

There is also one patch not included that allows target-core to limit
the number of fabric driver SGLs per I/O request using residuals, that
is currently required as a work-around for FC hosts which don't honor
EVPD block-limits settings.  At this point, it will most likely become
for-next material.

Thank you,

--nab
