While Ext4 was originally merged in 2.6.19, it was marked as a development filesystem. It has been a long time coming but as planned, Ext4dev has been renamed to Ext4 in 2.6.28 to indicate its level of maturity and paving the way for production level deployments. Ext4 filesystem developer Ted Tso also endorsed Btrfs as a multi-vendor, next generation filesystem and along with the interest from Andrew Morton, Btrfs is planned to be merged before 2.6.29 is released. It will follow a similar development process to Ext4 and be initially marked as development only.

The online defragmenter gives you the ability to defrag the filesystem without taking it offline, that's all, just a nice convenience not having to unmount or reboot to a "rescue" environment to do a defrag. Frankly I'm amazed it's taken 'til Ext4 for this to become a possibility, though there have been projects such as Shake that try to get around the lack of an official online defrag util for many filesystems. http://vleu.net/shake/

It depends on how big your files are. If you have 10GB free space and a 15GB file somewhere then you're going to struggle.
