Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger: "The highlights this round include: - Add target_alloc_session() w/ callback helper for doing se_session allocation + tag + se_node_acl lookup. (HCH + nab) - Tree-wide fabric driver conversion to use target_alloc_session() - Convert sbp-target to use percpu_ida tag pre-allocation, and TARGET_SCF_ACK_KREF I/O krefs (Chris Boot + nab) - Convert usb-gadget to use percpu_ida tag pre-allocation, and TARGET_SCF_ACK_KREF I/O krefs (Andrzej Pietrasiewicz + nab) - Convert xen-scsiback to use percpu_ida tag pre-allocation, and TARGET_SCF_ACK_KREF I/O krefs (Juergen Gross + nab) - Convert tcm_fc to use TARGET_SCF_ACK_KREF I/O + TMR krefs - Convert ib_srpt to use percpu_ida tag pre-allocation - Add DebugFS node for qla2xxx target sess list (Quinn) - Rework iser-target connection termination (Jenny + Sagi) - Convert iser-target to new CQ API (HCH) - Add pass-through WRITE_SAME support for IBLOCK (Mike Christie) - Introduce data_bitmap for asynchronous access of data area (Sheng Yang + Andy) - Fix target_release_cmd_kref shutdown comp leak (Himanshu Madhani) Also, there is a separate PULL request coming for cxgb4 NIC driver prerequisites for supporting hw iscsi segmentation offload (ISO), that will be the base for a number of v4.7 developments involving iscsi-target hw offloads" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (36 commits) target: Fix target_release_cmd_kref shutdown comp leak target: Avoid DataIN transfers for non-GOOD SAM status target/user: Report capability of handling out-of-order completions to userspace target/user: Fix size_t format-spec build warning target/user: Don't free expired command when time out target/user: Introduce data_bitmap, replace data_length/data_head/data_tail target/user: Free data ring in unified function target/user: Use iovec[] to describe continuous area target: Remove enum transport_lunflags_table target/iblock: pass WRITE_SAME to device if possible iser-target: Kill the ->isert_cmd back pointer in struct iser_tx_desc iser-target: Kill struct isert_rdma_wr iser-target: Convert to new CQ API iser-target: Split and properly type the login buffer iser-target: Remove ISER_RECV_DATA_SEG_LEN iser-target: Remove impossible condition from isert_wait_conn iser-target: Remove redundant wait in release_conn iser-target: Rework connection termination iser-target: Separate flows for np listeners and connections cma events iser-target: Add new state ISER_CONN_BOUND to isert_conn ...
