CentOS - Jan 2013 - default journal mode of ext3

Hi,

I found some articles (like https://bbs.archlinux.org/viewtopic.php?id=75152) on
the Internet saying that the default journal mode is writeback. Is that correct?
And is the journal mode of the following device writeback too? Thanks.

[root at localhost tmp]# tune2fs -l /dev/sda1
Default mount options:    user_xattr acl

mount man page says:
? data={journal|ordered|writeback}
????????????? Specifies the journalling? mode? for? file? data.?? Metadata? is
????????????? always? journaled.?? To use modes other than ordered on the root
????????????? filesystem, pass the mode to the kernel as boot parameter,? e.g.
????????????? rootflags=data=journal.

It seems to say that the defaults are:
? meta: always journaled
? data: ordered
