target: remove unused struct fields

2011-12-06T06:00:56Z

Some are never used, some are set but never read, dev_hoq_count is incremented and decremented, but never read. Signed-off-by: Joern Engel Signed-off-by: Nicholas Bellinger

target: remove the unused t_task_pt_sgl and t_task_pt_sgl_num se_cmd fields

target: remove the t_tasks_bidi se_cmd field

2011-12-06T06:00:53Z

And use a SCF_BIDI flag instead. Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: remove the t_tasks_fua se_cmd field

2011-12-06T06:00:52Z

target: remove the se_ordered_node se_cmd field

2011-12-06T06:00:52Z

We never walk ordered_cmd_list in the se_device, so remove all code related to supporting it. Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: remove the se_obj_ptr and se_orig_obj_ptr se_cmd fields

2011-12-06T06:00:52Z

We already have a perfectly valid se_device pointer in the command, so remove the mostly useless duplicates. Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: Avoid compiler warnings about signed one-bit bitfields

2011-12-06T06:00:50Z

Convert to unsigned bit fields for active I/O shutdown fields. Signed-off-by: Bart Van Assche Signed-off-by: Nicholas Bellinger

target: Address legacy PYX_TRANSPORT_* return code breakage

2011-12-06T06:00:49Z

This patch removes legacy usage of PYX_TRANSPORT_* return codes in a number of locations and addresses cases where transport_generic_request_failure() was returning the incorrect sense upon CHECK_CONDITION status after the v3.1 converson to use errno return codes. This includes the conversion of transport_generic_request_failure() to process cmd->scsi_sense_reason and handle extra TCM_RESERVATION_CONFLICT before calling transport_send_check_condition_and_sense() to queue up response status. It also drops PYX_TRANSPORT_OUT_OF_MEMORY_RESOURCES legacy usgae, and returns TCM_LOGICAL_UNIT_COMMUNICATION_FAILURE w/ a response for these cases. transport_generic_allocate_tasks(), transport_generic_new_cmd(), backend SCF_SCSI_DATA_SG_IO_CDB ->do_task(), and emulated ->execute_task() have all been updated to set se_cmd->scsi_sense_reason and return errno codes universally upon failure. This includes cmd->scsi_sense_reason assignment in target_core_alua.c, target_core_pr.c and target_core_cdb.c emulation code. Finally it updates fabric modules to remove the legacy usage, and for TFO->new_cmd_map() callers forwards return values outside of fabric code. iscsi-target has also been updated to remove a handful of special cases related to the cleanup and signaling QUEUE_FULL handling w/ ft_write_pending() (v2: Drop extra SCF_SCSI_CDB_EXCEPTION check during failure from transport_generic_new_cmd, and re-add missing task->task_error_status assignment in transport_complete_task) Cc: Christoph Hellwig Cc: stable@kernel.org Signed-off-by: Nicholas Bellinger
