    "different" is a key word here. why should we copy most of ext3 code
    into ext4?

    nope, we re-use existing i_data w/o any changes. yes, we've made
    inode a bit larger to cache last found extent. this improves
    performance in some workloads noticable though.

    would "#if CONFIG_EXT3_EXTENTS" be a good solution then?

    thanks. Alex
