iscsi-target: Refactor RX PDU logic + export request PDU handling
This patch refactors existing traditional iscsi RX side PDU handling to use iscsit_transport, and exports the necessary logic for external transport modules. This includes: - Refactor iscsit_handle_scsi_cmd() into PDU setup / processing - Add updated iscsit_handle_scsi_cmd() for tradtional iscsi code - Add iscsit_set_unsoliticed_dataout() wrapper - Refactor iscsit_handle_data_out() into PDU check / processing - Add updated iscsit_handle_data_out() for tradtional iscsi code - Add iscsit_handle_nop_out() + iscsit_handle_task_mgt_cmd() to accept pre-allocated struct iscsi_cmd - Add iscsit_build_r2ts_for_cmd() caller for iscsi_target_transport to handle ISTATE_SEND_R2T for TX immediate queue - Refactor main traditional iscsi iscsi_target_rx_thread() PDU switch into iscsi_target_rx_opcode() using iscsit_allocate_cmd() - Turn iscsi_target_rx_thread() process context into NOP for ib_isert side work-queue. v5 changes: - Make iscsit_handle_scsi_cmd() static (Fengguang) - Fix iscsit_handle_scsi_cmd() exception se_cmd leak (nab) v3 changes: - Add extra target_put_sess_cmd call in iscsit_add_reject_from_cmd after completion v2 changes: - Disable iscsit_ack_from_expstatsn() usage for RDMAExtentions=Yes - Disable iscsit_allocate_datain_req() usage for RDMAExtentions=Yes - Add target_get_sess_cmd() reference counting to iscsit_setup_scsi_cmd() - Add TFO->lio_check_stop_free() fabric API caller - Add export of iscsit_stop_dataout_timer() symbol - Add iscsit_build_r2ts_for_cmd() for iscsit_transport->iscsit_get_dataout() - Convert existing usage of iscsit_build_r2ts_for_cmd() to ->iscsit_get_dataout() - Drop RDMAExtentions=Yes specific check in iscsit_build_r2ts_for_cmd() - Fix RDMAExtentions -> RDMAExtensions typo (andy) - Pass correct dump_payload value into iscsit_get_immediate_data() for iscsit_handle_scsi_cmd() Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
