Of course! Okay now I'm begining to understand.

Why? Wouldn't both paths be valid options?

I'm very interested in this.
I'm not opposed to using struct page, but I'm confused as to how to start that. As I understand it, which is not well, defined a CONFIG_DISCONTIGMEM region to cover the Flash memory would add that to my pool of RAM. That would be 'bad', right? I don't see how to create the page structs and set this memory aside as different. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
