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

   - Introduce configfs support for unlocked configfs_depend_item()
     (krzysztof + andrezej)
   - Conversion of usb-gadget target driver to new function registration
     interface (andrzej + sebastian)
   - Enable qla2xxx FC target mode support for Extended Logins (himansu +
     giridhar)
   - Enable qla2xxx FC target mode support for Exchange Offload (himansu +
     giridhar)
   - Add qla2xxx FC target mode irq affinity notification + selective
     command queuing.  (quinn + himanshu)
   - Fix iscsi-target deadlock in se_node_acl configfs deletion (sagi +
     nab)
   - Convert se_node_acl configfs deletion + se_node_acl->queue_depth to
     proper se_session->sess_kref + target_get_session() usage.  (hch +
     sagi + nab)
   - Fix long-standing race between se_node_acl->acl_kref get and
     get_initiator_node_acl() lookup.  (hch + nab)
   - Fix target/user block-size handling, and make sure netlink reaches
     all network namespaces (sheng + andy)

  Note there is an outstanding bug-fix series for remote I_T nexus port
  TMR LUN_RESET has been posted and still being tested, and will likely
  become post -rc1 material at this point"
