+A config_item cannot live in a vacuum. The only way one can be created
is via mkdir(2) on a config_group. This will trigger creation of a
child item.
Finally, when userspace calls rmdir(2) on the item or group,
ct_group_ops->drop_item() is called. As a config_group is also a
-config_item, it is not necessary for a seperate drop_group() method.

The subsystem must config_item_put() the reference that was initialized
upon item allocation. If a subsystem has no work to do, it may omit
the ct_group_ops->drop_item() method, and configfs will call

"pending" directory does allow mkdir(2) and rmdir(2). An item is
created in the "pending" directory. Its attributes can be modified at

callback. If all required attributes are filled to satisfaction, the
method returns zero and the item is moved to the "live" directory.
