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

Pull SCSI target updates from Nicholas Bellinger:
 "Lots of activity in target land the last months.

  The highlights include:

   - Convert fabric drivers tree-wide to target_register_template() (hch
     + bart)

   - iser-target hardening fixes + v1.0 improvements (sagi)

   - Convert iscsi_thread_set usage to kthread.h + kill
     iscsi_target_tq.c (sagi + nab)

   - Add support for T10-PI WRITE_STRIP + READ_INSERT operation (mkp +
     sagi + nab)

   - DIF fixes for CONFIG_DEBUG_SG=y + UNMAP file emulation (akinobu +
     sagi + mkp)

   - Extended TCMU ABI v2 for future BIDI + DIF support (andy + ilias)

   - Fix COMPARE_AND_WRITE handling for NO_ALLLOC drivers (hch + nab)

  Thanks to everyone who contributed this round with new features,
  bug-reports, fixes, cleanups and improvements.

  Looking forward, it's currently shaping up to be a busy v4.2 as well"
