module_param( byte ... ) missing?

[Juergen Quade]

Rusty,

using the "byte"-datatype as module parameter throws a compile error.
Other than stated in the comment of the headerfile <linux/moduleparam.h>

	/* Helper functions: type is byte, short, ushort, int, uint, long,
	   ulong, charp, bool or invbool, or XXX if you define param_get_XXX,
	   param_set_XXX and param_check_XXX. */
	#define module_param_named(name, value, type, perm)
	...
	
the datatype _byte_ seems not be implemented.
Have you dropped it intentionally?

      Juergen.

No, just not implemented; the comment is overzealous.  

Of course, you can implement byte in two ways: you can do it in your
own module (effectively a private type), or in kernel/params.c.  I'd
prefer the former, and if lots of modules use it, we move it to
kernel/params.c.

Hope that clarifies,
Rusty.
