Subject: Re: [PATCH] scatterlist: Update size type to support greater then
 4GB size.

scatterlist elements longer than 4GB sound odd.  Please submit it
in a series with your actual user so that we can help figuring out
if it really makes sense or if there is a better way to solve your
problem.

As is this patch will massively increase the memory usage for all users
of struct scatterlist, so you better have a really good reason.
