Or data=ordered.  What does "cat /proc/mounts" say?  

The fsync() operation results in a journal commit operation, and if
you're using "data=ordered" or "data=journaled", the data blocks will
be flushed to either their final location on disk or to the journal
before the journal is allowed to commit.
