/*
 * Users often need to create attribute structures for their configurable
 * attributes, containing a configfs_attribute member and function pointers
 * for the show() and store() operations on that attribute. If they don't
 * need anything else on the extended attribute structure, they can use
 * this macro to define it  The argument _item is the name of the
 * config_item structure.
