Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger:
 "The most notable item is IBM virtual SCSI target driver, that was
  originally ported to target-core back in 2010 by Tomo-san, and has
  been brought forward to v4.x code by Bryant Ly, Michael Cyr and co
  over the last months.

  Also included are two ORDERED task related bug-fixes Bryant + Michael
  found along the way using ibmvscsis with AIX guests, plus a few
  miscellaneous target-core + iscsi-target bug-fixes with associated
  stable tags"

* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
  target: fix spelling mistake: "limitiation" -> "limitation"
  target: Fix residual overflow handling in target_complete_cmd_with_length
  tcm_fc: set and unset FCP_SPPF_TARG_FCN
  iscsi-target: Fix panic when adding second TCP connection to iSCSI session
  ibmvscsis: Initial commit of IBM VSCSI Tgt Driver
  target: Fix ordered task CHECK_CONDITION early exception handling
  target: Fix ordered task target_setup_cmd_from_cdb exception hang
  target: Fix max_unmap_lba_count calc overflow
  target: Fix race between iscsi-target connection shutdown + ABORT_TASK
  target: Fix missing complete during ABORT_TASK + CMD_T_FABRIC_STOP
