I think it's totally different story. Here I have block size smaller than page size and it's not new to the filesystem -- similar to 1k block size with 4k page size. So I was able to re-use most of infrastructure to handle the situation. Block size bigger than page size is backward task. I don't think I know enough to understand how hard it would be. I guess not easy. :) -- Kirill A. Shutemov -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx. For more info on Linux MM, see: http://www.linux-mm.org/ .
