iser-target: Add iSCSI Extensions for RDMA (iSER) target driverThis patch adds support for iSCSI Extensions for RDMA target mode,and includes CQ pooling per isert_device context distributed acrossmultiple active iser target sessions.It also uses cmwq process context for RX / TX ib_post_cq() pollingvia isert_cq_desc->cq_[rx,tx]_work invoked by isert_cq_[rx,tx]_callback()hardIRQ context callbacks.v5 changes:- Use ISER_RECV_DATA_SEG_LEN instead of hardcoded value in ISER_RX_PAD_SIZE (Or)- Fix make W=1 warnings (Or)- Add missing depends on NET && INFINIBAND_ADDR_TRANS in Kconfig (Randy + Or)- Make isert_device_find_by_ib_dev() return proper ERR_PTR (Wei Yongjun)- Properly setup iscsi_np->np_sockaddr in isert_setup_np() (Shlomi + nab)- Add special case for early ISCSI_OP_SCSI_CMD exception handling (nab)v4 changes:- Mark isert_cq_rx_work as static (Or)- Drop unnecessary ib_dma_sync_single_for_cpu + ib_dma_sync_single_for_device calls for isert_cmd->sense_buf_dma from isert_put_response (Or)- Use 12288 for ISER_RX_PAD_SIZE base to save extra page per struct iser_rx_desc (Or + nab)- Drop now unnecessary isert_rx_desc usage, and convert RX users to iser_rx_desc (Or + nab)- Move isert_[alloc,free]_rx_descriptors() ahead of isert_create_device_ib_res() usage (nab)- Mark isert_cq_[rx,tx]_callback() + prototypes as static- Fix 'warning: 'ret' may be used uninitialized' warning for isert_create_device_ib_res on powerpc allmodconfig (fengguang + nab)- Fix 'warning: 'ret' may be used uninitialized' warning for isert_connect_request on i386 allyesconfig (fengguang + nab)- Fix pr_debug conversion specification in isert_rx_completion() (fengguang + nab)- Drop unnecessary isert_conn->conn_cm_id != NULL check in isert_connect_release causing the build warning: "variable dereferenced before check 'isert_conn->conn_cm_id'"- Fix isert_lid + isert_np leak in isert_setup_np failure path- Add isert_conn->conn_wait_comp_err usage in isert_free_conn() for isert_cq_comp_err completion path- Add isert_conn->logout_posted bit to determine decrement of isert_conn->post_send_buf_count from logout response completion- Always set ISER_CONN_DOWN from isert_disconnect_work() callbackv3 changes:- Convert to use per isert_cq_desc->cq_[rx,tx]_work + drop tasklets (Or + nab)- Move IB_EVENT_QP_LAST_WQE_REACHED warn into correct isert_qp_event_callback (Or)- Drop unnecessary IB_ACCESS_REMOTE_* access flag usage in isert_create_device_ib_res (Or)- Add common isert_init_send_wr(), and convert isert_put_* calls (Or)- Move to verbs+core logic to single ib_isert.[c,h] (Or + nab)- Add kmem_cache isert_cmd_cache usage for descriptor allocation (nab)- Move common ib_post_send() logic used by isert_put_*() to isert_post_response() (nab)- Add isert_put_reject call in isert_response_queue() for posting ISCSI_REJECT response.
