<div class='commit-subject'>Merge git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending</div><div class='commit-msg'>Pull SCSI target fixes from Nicholas Bellinger:
 "This target series for v4.10 contains fixes which address a few
  long-standing bugs that DATERA's QA + automation teams have uncovered
  while putting v4.1.y target code into production usage.

  We've been running the top three in our nightly automated regression
  runs for the last two months, and the COMPARE_AND_WRITE fix Mr. Gary
  Guo has been manually verifying against a four node ESX cluster this
  past week.

  Note all of them have CC' stable tags.

  Summary:

   - Fix a bug with ESX EXTENDED_COPY + SAM_STAT_RESERVATION_CONFLICT
     status, where target_core_xcopy.c logic was incorrectly returning
     SAM_STAT_CHECK_CONDITION for all non SAM_STAT_GOOD cases (Nixon
     Vincent)

   - Fix a TMR LUN_RESET hung task bug while other in-flight TMRs are
     being aborted, before the new one had been dispatched into tmr_wq
     (Rob Millner)

   - Fix a long standing double free OOPs, where a dynamically generated
     'demo-mode' NodeACL has multiple sessions associated with it, and
     the /sys/kernel/config/target/$FABRIC/$WWN/ subsequently disables
     demo-mode, but never converts the dynamic ACL into a explicit ACL
     (Rob Millner)

   - Fix a long standing reference leak with ESX VAAI COMPARE_AND_WRITE
     when the second phase WRITE COMMIT command fails, resulting in
     CHECK_CONDITION response never being sent and se_cmd-&gt;cmd_kref
     never reaching zero (Gary Guo)

  Beyond these items on v4.1.y we've reproduced, fixed, and run through
  our regression test suite using iscsi-target exports, there are two
  additional outstanding list items:

   - Remove a &gt;= v4.2 RCU conversion BUG_ON that would trigger when
     dynamic node NodeACLs where being converted to explicit NodeACLs.
     The patch drops the BUG_ON to follow how pre RCU conversion worked
     for this special case (Benjamin Estrabaud)

   - Add ibmvscsis target_core_fabric_ops-&gt;max_data_sg_nent assignment
     to match what IBM's Virtual SCSI hypervisor is already enforcing at
     transport layer. (Bryant Ly + Steven Royer)"

* git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
  ibmvscsis: Add SGL limit
  target: Fix COMPARE_AND_WRITE ref leak for non GOOD status
  target: Fix multi-session dynamic se_node_acl double free OOPs
  target: Fix early transport_generic_handle_tmr abort scenario
  target: Use correct SCSI status during EXTENDED_COPY exception
  target: Don't BUG_ON during NodeACL dynamic -&gt; explicit conversion
