target: Propigate up ->cmd_kref put return via transport_generic_free_cmd

2013-05-31T08:21:23Z

Go ahead and propigate up the ->cmd_kref put return value from target_put_sess_cmd() -> transport_release_cmd() -> transport_put_cmd() -> transport_generic_free_cmd(). This is useful for certain fabrics when determining the active I/O shutdown case with SCF_ACK_KREF where a final target_put_sess_cmd() is still required by the caller.

target: Re-instate sess_wait_list for target_wait_for_sess_cmds

2013-05-30T04:30:33Z

Switch back to pre commit 1c7b13fe652 list splicing logic for active I/O shutdown with tcm_qla2xxx + ib_srpt fabrics. The original commit was done under the incorrect assumption that it's safe to walk se_sess->sess_cmd_list unprotected in target_wait_for_sess_cmds() after sess->sess_tearing_down = 1 has been set by target_sess_cmd_list_set_waiting() during session shutdown. So instead of adding sess->sess_cmd_lock protection around sess->sess_cmd_list during target_wait_for_sess_cmds(), switch back to sess->sess_wait_list to allow wait_for_completion() + TFO->release_cmd() to occur without having to walk ->sess_cmd_list after the list_splice. Also add a check to exit if target_sess_cmd_list_set_waiting() has already been called, and add a WARN_ON to check for any fabric bug where new se_cmds are added to sess->sess_cmd_list after sess->sess_tearing_down = 1 has already been set.

2013-05-21T04:44:10Z

Drop unused transport_wait_for_tasks() check in target_wait_for_sess_cmds shutdown code, and convert tcm_qla2xxx + ib_srpt fabric drivers. Cc: Joern Engel Cc: Roland Dreier Signed-off-by: Nicholas Bellinger

iscsi-target: Add iscsit_transport API template

2013-04-25T08:05:26Z

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

target: Add export of target_get_sess_cmd symbol

2013-04-25T08:05:26Z

Export target_get_sess_cmd() symbol so that it can be used by iscsi-target. Signed-off-by: Nicholas Bellinger

target: Add sbc_execute_unmap() helper

2013-04-25T08:05:24Z

iblock_execute_unmap() and fd_execute_unmap share a lot of code. Add sbc_execute_unmap() helper to remove duplicated code for iblock_execute_unmap() and fd_execute_unmap(). Cc: Christoph Hellwig Cc: Martin K. Petersen Cc: Nicholas Bellinger Signed-off-by: Asias He Signed-off-by: Nicholas Bellinger

target: Rename spc_get_write_same_sectors -> sbc_get_write_same_sectors

2013-02-23T20:46:14Z

Trivial, but WRITE SAME is an SBC command so it seems strange for a related function (defined in target_core_sbc.c) to be in the spc_ namespace. Signed-off-by: Roland Dreier Signed-off-by: Nicholas Bellinger
