Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger: "Here are the outstanding target pending updates for v4.7-rc1. 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" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (29 commits) iscsi-target: Fix early sk_data_ready LOGIN_FLAGS_READY race cxgbit: Use type ISCSI_CXGBIT + cxgbit tpg_np attribute iscsi-target: Convert transport drivers to signal rdma_shutdown iscsi-target: Make iscsi_tpg_np driver show/store use generic code tcm_qla2xxx Add SCSI command jammer/discard capability iscsi-target: graceful disconnect on invalid mapping to iovec target: need_to_release is always false, remove redundant check and kfree target: remove sess_kref and ->shutdown_session iscsi-target: remove usage of ->shutdown_session tcm_qla2xxx: introduce a private sess_kref target: make close_session optional target: make ->shutdown_session optional target: remove acl_stop target: consolidate and fix session shutdown cxgbit: add files for cxgbit.ko iscsi-target: export symbols iscsi-target: call complete on conn_logout_comp iscsi-target: clear tx_thread_active iscsi-target: add new offload transport type iscsi-target: use conn_transport->transport_type in text rsp ...
