Nicholas Bellinger 3f99306337 iscsi-target: Add iscsit_transport API template ... Add basic struct iscsit_transport API template to allow iscsi-target for running with external transport modules using existing iscsi_target_core.h code. For all external modules, this calls try_module_get() and module_put() to obtain + release an external iscsit_transport module reference count. Also include the iscsi-target symbols necessary in iscsi_transport.h to allow external transport modules to function. v3 changes: - Add iscsit_build_reject export for ISTATE_SEND_REJECT usage v2 changes: - Drop unnecessary export of iscsit_get_transport + iscsit_put_transport (roland) - Add ->iscsit_queue_data_in() to remove extra context switch on RDMA_WRITE - Add ->iscsit_queue_status() to remove extra context switch on IB_SEND status - Add ->iscsit_get_dataout() to remove extra context switch on RDMA_READ - Drop ->iscsit_free_cmd() - Drop ->iscsit_unmap_cmd() - Rename iscsit_create_transport() -> iscsit_register_transport() (andy) - Rename iscsit_destroy_transport() -> iscsit_unregister_transport() (andy) Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>		2013-04-25 01:05:26 -07:00
