These macros are portable ways to declare kernel module parameters. They must be used in the global scope, and are not followed by a terminating semicolon. They must be used after the associated variable or function has been defined.
EXPORT_FUNCTION makes a symbol available for use by a subsequently loaded component. It is unrelated to hal functions, which are described in hal_export_funct(3hal)
Not available in userspace code.
