Pull SCSI target fixes from Nicholas Bellinger:
 "The first patch is to address a long standing issue where INQUIRY
  vendor + model response data was not correctly padded with ASCII
  spaces, causing MSFT and Falconstor multipath stacks to not function
  with our LUNs.

  The second -> forth patches are additional iscsi-target regression
  fixes for the post >= v3.10 iser-target changes.  The second and third
  are failure cases that have appeared during further testing, and the
  forth is only reproducible with malformed NOP packets.

  The fifth patch is a v3.11 specific regression caused by a recent
  optimization that showed up during WRITE I/O failure testing.

  I'll be sending Patch #1 and Patch #5 to Greg-KH separately for
  stable"

* git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
  target: Fix se_cmd->state_list leak regression during WRITE failure
  iscsi-target: Fix potential NULL pointer in solicited NOPOUT reject
  iscsi-target: Fix iscsit_transport reference leak during NP thread reset
  iscsi-target: Fix ImmediateData=Yes failure regression in >= v3.10
  target: Fix trailing ASCII space usage in INQUIRY vendor+model
