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

Pull SCSI target fixes from Nicholas Bellinger:
 "This includes fixes from HCH for -rc1 configfs default_groups
  conversion changes that ended up breaking some iscsi-target
  default_groups, along with Sagi's ib_drain_qp() conversion for
  iser-target to use the common caller now available to RDMA kernel
  consumers in v4.6+ code"

* git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
  target: add a new add_wwn_groups fabrics method
  target: initialize the nacl base CIT begfore init_nodeacl
  target: remove ->fabric_cleanup_nodeacl
  iser-target: Use ib_drain_qp
