[An Example]

+subsystem/group and the simple_child item in configfs_example_explicit.c
+and configfs_example_macros.c. It shows a trivial object displaying and
+storing an attribute, and a simple group creating and destroying these
+children.
+
+The only difference between configfs_example_explicit.c and
+configfs_example_macros.c is how the attributes of the childless item
+are defined. The childless item has extended attributes, each with
+their own show()/store() operation. This follows a convention commonly
+used in sysfs. configfs_example_explicit.c creates these attributes
+by explicitly defining the structures involved. Conversely
+configfs_example_macros.c uses some convenience macros from configfs.h
+to define the attributes. These macros are similar to their sysfs
+counterparts.
