The init function is used to customize the helper process prior to exec. A non-zero return code causes the process to error out, exit, and return the failure to the calling process
The cleanup function is just before ethe subprocess_info is about to be freed. This can be used for freeing the argv and envp. The Function must be runnable in either a process context or the context in which call_usermodehelper_exec is called.
