Please see Li Xi's recent email "Directory/Project quota supports" on
the linux-ext4 list. He has already added some prototype support for
project quotas to quota-tools.
I think it might make sense to keep the same API as XFS for the ext4
quotas (to keep compatibility for existing XFS deployments), but add
support into quota-tools so that it is usable by all filesystems.
