函数名称：moyo_assign_domain - Create a domain or a namespace.*@domainname: The name of domain.*@transit: True if transit to domain found or created.* Returns pointer to "struct tomoyo_domain_info" on success, NULL otherwise.* Caller holds tomoyo_read_lock().

函数原型：struct tomoyo_domain_info *tomoyo_assign_domain(const char *domainname, const bool transit)

返回类型：struct tomoyo_domain_info
