[GIT PULL] target fixes for v4.3-rc3

[Nicholas A. Bellinger]

Hi Linus,

Here are the outstanding target-pending fixes for v4.3-rc3 code.

Please go ahead and pull from:

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

This includes a iser-target series from Jenny + Sagi @ Mellanox that
addresses the few remaining active I/O shutdown bugs, along with a patch
to support zero-copy for immediate data payloads that gives a nice
performance improvement for small block WRITEs. 

Also included are some recent >= v4.2 regression bug-fixes.  The most
notable is a RCU conversion regression for SPC-3 PR registrations, and
recent removal of obsolete RFC-3720 markers that introduced a login
regression bug with MSFT iSCSI initiators.

Thanks to everyone who has been testing + reporting bugs for v4.x.
