Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending

Pull SCSI target updates from Nicholas Bellinger:
 "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.

  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"
