Do we need it? Yes.

Hi all, this series removes most users of the write_one_page API. These helpers internally call ->writepage which we are gradually removing from the kernel. Changes since v2: - more minix error handling fixes Changes since v1: - drop the btrfs changes (queue up in the btrfs tree) - drop the finaly move to jfs (can't be done without the btrfs patches) - fix the existing minix code to
