It has been discussed in the conference call that we need to better define the requirements for ext4 and set some kind of target for when new function should be added, so we can then work on stabilizing the code and getting it production-ready. The list below is based on the candidate features list in Documentation/filesystems/ext4.txt. It is by no means complete, as some other ideas are being floated around, and I very well may have missed some features. I plan to put this in a wiki, but I'm not sure what the best place is. Neither http://fedoraproject.org/wiki/ext3-devel nor https://mail.clusterfs.com/wikis/lustre/Ext3Development has been kept up to date, but I'd be happy to use either.
