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 v3.17-rc6.
Included are Sagi's long overdue fixes related to iser-target
shutdown, along with a couple of fixes from Sebastian related to ALUA
Referrals changes that when in during the v3.14 time-frame.
Also included are a few iscsi-target fixes, most recently of which
where found during Joern's Coverity scanning of target code"
* git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
iscsi-target: avoid NULL pointer in iscsi_copy_param_list failure
iscsi-target: Fix memory corruption in iscsit_logout_post_handler_diffcid
target: Fix inverted logic in SE_DEV_ALUA_SUPPORT_STATE_STORE
target: Fix user data segment multiplier in spc_emulate_evpd_b3()
iscsi-target: Ignore ICF_GOT_LAST_DATAOUT during Data-Out ITT lookup
Target/iser: Fix initiator_depth and responder_resources
Target/iser: Avoid calling rdma_disconnect twice
Target/iser: Don't put isert_conn inside disconnected handler
Target/iser: Get isert_conn reference once got to connected_handler
