e4defrag is not in the release branch of e2fsprogs and as such we did not 
include it. I played with it and also provided feedback to the ext4 list,
but the results were not good enough to promote it - not yet. But my feedback
got quite some discussions and patches started, so I'm very confident with
our decision to go with ext4.
