target: Use a PASSTHROUGH flag instead of transport_types

2015-05-31T02:58:11+00:00

It seems like we only care if a transport is passthrough or not. Convert
transport_type to a flags field and replace TRANSPORT_PLUGIN_* with a
flag, TRANSPORT_FLAG_PASSTHROUGH.

target: Fix se_tpg_tfo->tf_subsys regression + remove tf_subsystem

2015-05-31T01:04:20+00:00

There is just one configfs subsystem in the target code, so we might as
well add two helpers to reference / unreference it from the core code
instead of passing pointers to it around.

This fixes a regression introduced for v4.1-rc1 with commit 9ac8928e6,
where configfs_depend_item() callers using se_tpg_tfo->tf_subsys would
fail, because the assignment from the original target_core_subsystem[]
is no longer happening at target_register_template() time.

(Fix target_core_exit_configfs pointer dereference - Sagi)

target: simplify the target template registration API

2015-04-14T19:28:41+00:00

Instead of calling target_fabric_configfs_init() +
target_fabric_configfs_register() / target_fabric_configfs_deregister()
target_fabric_configfs_free() from every target driver, rewrite the API
so that we have simple register/unregister functions that operate on
a const operations vector.

This patch also fixes a memory leak in several target drivers. Several
target drivers namely called target_fabric_configfs_deregister()
without calling target_fabric_configfs_free().

A large part of this patch is based on earlier changes from
Bart Van Assche .

(v2: Add a new TF_CIT_SETUP_DRV macro so that the core configfs code
can declare attributes as either core only or for drivers)

target: Convert fabric module autoload failures to pr_debug

2015-03-20T18:36:50+00:00

This patch converts the fabric module autoload failures from
pr_err to pr_debug in target_core_register_fabric() code, to
reduce the amount of noise during normal operation.

target: Drop left-over internal dev attribute code

2014-12-02T05:36:21+00:00

Now that backend drivers are populating their own device attributes,
go ahead and remove left-over definitions + internal attribute list
of device attributes from target_core_configfs.c code

Also update TB_CIT_SETUP(dev_attrib,...) to signal ct_attr = NULL.

target: Move dev_stat_cit to struct se_subsystem_api

2014-12-02T05:35:39+00:00

This patch adds support for dev_stat_cit as an external config_item_type
using TB_CIT_SETUP() helper macro, and sets only ct_group_ops following
existing code.

It updates target_core_make_subdev() + target_core_setup_dev_attrib_cit() +
struct target_backend_cits, and drops left-over target_core_dev_stat_cit
from target_core_configfs.c code and update comments.

This patch introduces no functional change from existing code.
