   2 * This module emits "Hello, world" on printk when loaded.
   3 *
   4 * It is designed to be used for basic evaluation of the module loading
   5 * subsystem (for example when validating module signing/verification). It
   6 * lacks any extra dependencies, and will not normally be loaded by the
   7 * system unless explicitly requested by name.
