Hello Linus,

Here are the target updates for v4.6-rc1 code.

Please go ahead and pull from:

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

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.

Thank you,
