target: Add EXPORT_SYMBOL for existing se_dev_set_*

2014-12-02T05:36:02Z

Now that target_core_backend_configfs.h macros will be using these se_dev_set attribute functions externally to allow backend drivers to populate different attributes, go ahead and add EXPORT_SYMBOL() for the existing default set of 30 device attributes. Also update target_core_backend.h with proper function prototypes. Signed-off-by: Nicholas Bellinger

target: Add force_pr_aptpl device attribute

2014-10-04T05:41:20Z

This patch adds a force_pr_aptpl device attribute used to force SPC-3 PR Activate Persistence across Target Power Loss (APTPL) operation. This makes PR metadata write-out occur during state change regardless if new PERSISTENT_RESERVE_OUT CDBs have their APTPL feature bit set. This is useful during H/A failover in active/passive setups where all PR state is being re-created on a different node, driven by configfs backend device + export layout and pre-loaded $DEV/pr/res_aptpl_metadata.

target: Change core_dev_del_lun to take a se_lun instead of unpacked_lun

2014-10-01T21:38:48Z

Remove core_tpg_pre_dellun entirely, since we don't need to get/check a pointer we already have. Nothing else can return an error, so core_dev_del_lun can return void. Rename core_tpg_post_dellun to remove_lun - a clearer name, now that pre_dellun is gone. Reviewed-by: Christoph Hellwig Signed-off-by: Andy Grover Signed-off-by: Nicholas Bellinger

target: core_tpg_post_dellun can return void

target/configfs: Expose protection device attributes

2014-01-18T09:57:47Z

This patch adds support for exposing DIF protection device attributes via configfs. This includes: pi_prot_type: Protection Type (0, 1, 3 currently support) pi_prot_format: Protection Format Operation (FILEIO only) Within se_dev_set_pi_prot_type() it also adds the se_subsystem_api device callbacks to setup per device protection information. v2 changes: - Drop pi_guard_type + pi_prot_version related code (MKP) - Add pi_prot_format logic (Sagi) - Add ->free_prot callback in target_free_device - Add hw_pi_prot_type read-only attribute Cc: Martin K.

target: Don't use void* when passing dev in core_tpg_add_lun

Especially since it's actually a device. Signed-off-by: Andy Grover Signed-off-by: Nicholas Bellinger

target: Rename core_tpg_{pre,post}_addlun for clarity

2013-12-16T21:28:19Z

"pre" is really an allocation function. The only time it isn't called is for virtual_lun0, which is statically allocated. Renaming that to "alloc" lets the other function not need to be "post", and just be called core_tpg_add_lun. (nab: fix minor applying fuzz in core_tpg_setup_virtual_lun0) Signed-off-by: Andy Grover Signed-off-by: Nicholas Bellinger

target: Add percpu refcounting for se_lun access

2013-11-07T22:24:52Z

This patch adds percpu refcounting for se_lun access that allows the association of an se_lun + se_cmd in transport_lookup_cmd_lun() to occur without an extra list_head for tracking outstanding I/O during se_lun shutdown. This effectively changes se_lun shutdown logic to wait for outstanding I/O percpu references to complete in transport_lun_remove_cmd() using se_lun->lun_ref_comp, instead of explicitly draining the per se_lun command list and waiting for individual se_cmd descriptor processing to complete.

target: Add Third Party Copy (3PC) bit in INQUIRY response

2013-09-10T23:48:46Z

This patch adds the Third Party Copy (3PC) bit to signal support for EXTENDED_COPY within standard inquiry response data. Also add emulate_3pc device attribute in configfs (enabled by default) to allow the exposure of this bit to be disabled, if necessary.
