Subject: target: Move dev_attrib_cit to struct se_subsystem_api
X-Git-Tag: firefly_0821_release~176^2~2611^2~49
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=f79a897efa6a95d698c4064e48e0a5afddc0ad9f;p=firefly-linux-kernel-4.4.55.git

target: Move dev_attrib_cit to struct se_subsystem_api

This patch adds support for dev_attrib_cit as an external config_item_type
using TB_CIT_SETUP() helper macro, and sets both ct_item_ops + ct_attr
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_attrib_cit
from target_core_configfs.c code and update comments.

This patch introduces no functional change from existing code.
