target: Alter core_pr_dump_initiator_port for ease of use

2013-06-14T07:04:31Z

We use this function exclusively in debug prints. Instead of returning 0 or 1 if isid is present, just set buf to "" if it isn't there. This saves callers from having to check the return value. Signed-off-by: Andy Grover Signed-off-by: Nicholas Bellinger

target: pass sense_reason as a return value

2012-11-07T04:55:46Z

Pass the sense reason as an explicit return value from the I/O submission path instead of storing it in struct se_cmd and using negative return values. This cleans up a lot of the code pathes, and with the sparse annotations for the new sense_reason_t type allows for much better error checking. (nab: Convert spc_emulate_modesense + spc_emulate_modeselect to use sense_reason_t with Roland's MODE SELECT changes) Signed-off-by: Christoph Hellwig Cc: Roland Dreier Signed-off-by: Nicholas Bellinger

target: simplify reservations code

2012-11-07T04:55:45Z

We do not support host-level reservations for the pscsi backend, and all virtual backends are newere than SCSI-2, so just make the combined SPC-3 + SCSI-2 support the only supported variant and kill the switches for the different implementations, given that this code handles the no-op version just fine. (hch: Update DRF_SPC2_RESERVATIONS lock usage) Signed-off-by: Christoph Hellwig

target: kill struct se_subsystem_dev

2012-11-07T04:55:43Z

Simplify the code a lot by killing the superflous struct se_subsystem_dev. Instead se_device is allocated early on by the backend driver, which allocates it as part of its own per-device structure, borrowing the scheme that is for example used for inode allocation.

target: replace ->execute_task with ->execute_cmd

2012-05-06T22:11:14Z

Make CDB emulation work on commands instead of tasks again as a preparation of removing tasks completely. Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: Move core_scsi3_check_cdb_abort_and_preempt

2011-12-14T11:27:34Z

And make it static afterwards. Signed-off-by: Joern Engel Signed-off-by: Nicholas Bellinger

target: pass the se_task to the CDB emulation callback

2011-11-04T08:00:17Z

We want to be able to handle all CDBs through it and remove hacks like always using the first task in a CDB in target_report_luns. Also rename the callback to ->execute_task to better describe its use. Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: split core_scsi3_emulate_pr

2011-11-04T08:00:17Z

Split core_scsi2_emulate_crh into one routine each for the PERSISTENT_RESERVE_IN and PERSISTENT_RESERVE_OUT side. Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: split core_scsi2_emulate_crh

2011-11-04T08:00:08Z

Split core_scsi2_emulate_crh into one routine each for the reserve and release side. The common code now is in a helper called by both routines. Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: Core cleanups from AGrover (round 1)

2011-07-22T09:37:43Z

This patch contains the squashed version of a number of cleanups and minor fixes from Andy's initial series (round 1) for target core this past spring. The condensed log looks like: target: use errno values instead of returning -1 for everything target: Rename transport_calc_sg_num to transport_init_task_sg target: Fix leak in error path in transport_init_task_sg target/pscsi: Remove pscsi_get_sh() usage target: Make two runtime checks into WARN_ONs target: Remove hba queue depth and convert to spin_lock_irq usage target: dev->dev_status_queue_obj is unused target: Make struct se_queue_req.cmd type struct se_cmd * target: Remove __transport_get_qr_from_queue() target: Rename se_dev->g_se_dev_list to se_dev_node target: Remove struct se_global target: Simplify scsi mib index table code target: Make dev_queue_obj a member of se_device instead of a pointer target: remove extraneous returns at end of void functions target: Ensure transport_dump_vpd_ident_type returns null-terminated str target: Function pointers don't need to use '&' to be assigned target: Fix comment in __transport_execute_tasks() target: Misc style cleanups target: rename struct pr_reservation_template to pr_reservation target: Remove #defines that just perform indirection target: Inline transport_get_task_from_execute_queue() target: Minor header comment fixes Signed-off-by: Andy Grover Signed-off-by: Nicholas Bellinger
