    Subject[36/37] Large blocksize support for ext2
    This adds support for a block size of up to 64k on any platform.
    It enables the mounting filesystems that have a larger blocksize
    than the page size.

    F.e. the following is possible on x86_64 and i386 that have only a 4k page

    mke2fs -b 16384 /dev/hdd2 <Ignore warning about too large block size>

    mount /dev/hdd2 /media
    ls -l /media

    .... Do more things with the volume that uses a 16k page cache size on
    a 4k page sized platform..

    Hmmm... Actually there is nothing additional to be done after the earlier
    cleanup of the macros. So just modify copyright.
