Merge branch 'for-next-merge' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending

Pull SCSI target update from Nicholas Bellinger:
 "The highlights this round include:

   - Add fileio support for WRITE_SAME w/ UNMAP=1 discard (asias)
   - Add fileio support for UNMAP discard (asias)
   - Add tcm_vhost hotplug support to work with upstream QEMU
     vhost-scsi-pci code (asias + mst)
   - Check for aborted sequence in tcm_fc response path (mdr)
   - Add initial iscsit_transport support into iscsi-target code (nab)
   - Refactor iscsi-target RX PDU logic + export request PDU handling
     (nab)
   - Refactor iscsi-target TX queue logic + export response PDU creation
     (nab)
   - Add new iSCSI Extentions for RDMA (ISER) target driver (Or + nab)

  The biggest changes revolve around iscsi-target refactoring in order
  to support the iser-target driver.  This includes the conversion of
  the iscsi-target data-path to use modern se_cmd->cmd_kref counting,
  and allowing transport independent aspects of RX/TX PDU
  request/response handling be shared across existing traditional
  iscsi-target code, and the new iser-target code.

  Thanks to Or Gerlitz + Mellanox for supporting the iser-target
  development effort!"
