Actually not. The quotas in ext3 are transactional as well. It's just
that the "ext3" journal layer allows nested transactions, so it is possible
to start a write transaction, call into the journal code which calls back
into the ext3 write code to start a nested transaction on the journal file
(i.e. it is in the same transaction as the initial write), and then the
initial write completes.
Cheers, Andreas
