- I've got a defragmenter working for extfs. It works - it successcully
- defragmented a 90% full 100MB partition for me, and cut the time for a
- full boot into xdm from 38 to 27 seconds. (This was at a point where
- frag was reporting something like 50% block fragmentation). But - in
- its current state it thrashes the disk somewhat; there are a lot of
- optimisations I would want to do before releasing it (like buffering
- and sorting reads). It's based on the efsck code, so the inode/indtab
- walking ought to be correct. Is there much interest in getting this
- thing tidied up?

- Cheers,
