    Struct scatterlist must contain, at a minimum, the following
    members:
 
-	char *address;
 	struct page *page;
 	unsigned int offset;
 	unsigned int length;
 
-   The "address" member will disappear in 2.5.x

    interfaces dealing with scatterlists must be able to cope
    properly with page being non NULL.

-   In 2.5.x, all scatterlists will use "page+offset".  But during
