A lun is "opened" on storing the "file" attribute of the lun, it is in fsg_lun_store_file, storage_common.c. So, again, this is a configfs callback. On storing the connect attribute, the following happens: a composite driver is probed, then all the configurations are iterated over, their functions being bound in turn. After the gadget is set up this way, the host notices connecting a new mass storage device.
The configuration has to remain unchanged until the "connect" attribute is changed (i.e. unconnected). That means the gadget can only be reconfigured once it is not active.
So it seems the only chance to call config_item_depend is in a configfs callback. Or is it? Thanks, Andrzej
