[GIT PULL] target updates for v3.15-rc1

[Nicholas A. Bellinger]

Hello Linus!

Here are the target pending updates for v3.15-rc1.  Apologies in advance
for waiting until the second to last day of the merge window to send
these out.

Please go ahead and pull from:

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

The highlights this round include:

  - iser-target support for T10 PI (DIF) offloads (Sagi + Or)
  - Fix Task Aborted Status (TAS) handling in target-core (Alex Leung)
  - Pass in transport supported PI at session initialization (Sagi + MKP + nab)
  - Add WRITE_INSERT + READ_STRIP T10 PI support in target-core (nab + Sagi)
  - Fix iscsi-target ERL=2 ASYNC_EVENT connection pointer bug (nab)
  - Fix tcm_fc use-after-free of ft_tpg (Andy Grover)
  - Use correct ib_sg_dma primitives in ib_isert (Mike Marciniszyn)

Also, note the virtio-scsi + vhost-scsi changes to expose T10 PI
metadata into KVM guest have been left-out for now, as there where a few
comments from MST + Paolo that where not able to be addressed in time
for v3.15.  Please expect this feature for v3.16-rc1.

Thank you,
