[GIT PULL] target updates for v4.7-rc1

[Nicholas A. Bellinger]

Hi Linus,

Here are the outstanding target pending updates for v4.7-rc1.

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:

- Allow external PR/ALUA metadata path be defined at runtime via
  top level configfs attribute. (Lee)
- Fix target session shutdown bug for ib_srpt multi-channel. (hch)
- Make TFO close_session() and shutdown_session() optional. (hch)
- Drop se_sess->sess_kref + convert tcm_qla2xxx to internal kref. (hch)
- Add tcm_qla2xxx endpoint attribute for basic FC jammer. (Laurence)
- Refactor iscsi-target RX/TX PDU encode/decode into common code. (Varun)
- Extend iscsit_transport with xmit_pdu, release_cmd, get_rx_pdu,
  validate_parameters, and get_r2t_ttt for generic ISO offload. (Varun)
- Initial merge of cxgb iscsi-segment offload target driver. (Varun)

The bulk of the changes are Chelsio's new driver, along with a number of
iscsi-target common code improvements made by Varun + Co along the way.

Thank you,

--nab
