This comes from modern target_fabric_drop_wwn() -> config_item_put() ->
config_group_put() releasing the top level fabric config_group @
port->port_wwn.wwn_group before the last config_item_put() -> struct
configfs_group_operations->drop_item() -> TFO->drop_wwn() ->
srpt_drop_tport() has been invoked.
The informational config_item_name() also appears in a handful of other
fabric TFO->drop_wwn() code, which is really left-over usage from pre v4
target_core_fabric_configfs.c days when struct config_group was setup
and released directly by the fabrics.
Anyways, I'll go ahead and drop this legacy usage of config_item_name()
tree-wide. Thanks for pointing this out.
