Btrfs: fix missing last-entry in readdir(3) When one does a 32-bit readdir(3), the last entry of a directory is missing. This is however not due to passing a large value to filldir, but it seems to have to do with glibc doing telldir or something quirky. In any case, this patch fixes it in practice.
