    FWIW, being able to have large (8-64kB) blocksize would be great for
    ext2/3/4. We'd sort of been betting on this by limiting the on-disk
    extent format to 48-bit physical block numbers, and to have 2 patches
    to implement this in as many weeks is excellent.

    To me the mechanism doesn't matter, whether through fsblock or high-order
    PAGE_SIZE. I'll let the rest of you duke it out as long as at least one
    of them makes it into the kernel.

    Cheers, Andreas
