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

Pull SCSI target fixes from Nicholas Bellinger:
 "Here are the target-pending fixes for v4.12-rc4:

   - ibmviscsis ABORT_TASK handling fixes that missed the v4.12 merge
     window. (Bryant Ly and Michael Cyr)

   - Re-add a target-core check enforcing WRITE overflow reject that was
     relaxed in v4.3, to avoid unsupported iscsi-target immediate data
     overflow. (nab)

   - Fix a target-core-user OOPs during device removal. (MNC + Bryant
     Ly)

   - Fix a long standing iscsi-target potential issue where kthread exit
     did not wait for kthread_should_stop(). (Jiang Yi)

   - Fix a iscsi-target v3.12.y regression OOPs involving initial login
     PDU processing during asynchronous TCP connection close. (MNC +
     nab)

  This is a little larger than usual for an -rc4, primarily due to the
  iscsi-target v3.12.y regression OOPs bug-fix.

  However, it's an important patch as MNC + Hannes where both able to
  trigger it using a reduced iscsi initiator login timeout combined with
  a backend taking a long time to complete I/Os during iscsi login
  driven session reinstatement"
