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