Summary by cubic

Refactors the multi-file module example to use the standard module_init and module_exit macros instead of the legacy init_module and cleanup_module entry points.

  • start.c and stop.c now define static __init and __exit functions and register them with the appropriate macros.
  • Adds linux/init.h include for the macro definitions.

Closes #388
