Reiserfs is not a journalised filesystem.
It's an atomic one, so there's no need for a journal.

An atomic filesystem means a transaction is completed or not completed, not half completed 3/4 completed, etc. etc, To make a filesystem atomic we use logs meta-data logging as in Reiser3 or wandering logs as in Reiser4.
