I can't answer the question as to why, although I suspect because it's a lot easier, I can say, however, that if gfp were to not return contiguous pages, it would break my driver. -- Timur Tabi - ttabi@interactivesi.com Interactive Silicon - http://www.interactivesi.com When replying to a mailing-list message, please direct the reply to the mailing list only.
