Bill,

Principle of patch looks fine, but the formatting is all messed
up. Could you please try to clean it up a bit and resend it? If your
mail client auto-wraps it, please try sending it as an attachment.

In general code and comments should stay within 80 characters as with
the kernel.

Sorry for the late response, I missed your posting as I was traveling at
the time. Thanks to Neil for nagged me about it.

Cheers,
Jes
