Default mount options ignored on ext3

[=?ISO-8859-2?Q?Krzysztof_Ol=EAdzki?=]

Hello,

It seems that "Default mount options" from ext3 fs is ignored by
the linux kernel. I have just set "Default mount options" to
"journal_data" on my root fs but kernel still mounts it with
journal_data_ordered:

(part of dmesg)
EXT3-fs: mounted filesystem with ordered data mode.
                                 ~~~~~~~~~~~~~~~~~
VFS: Mounted root (ext3 filesystem) readonly.

$ tune2fs -l /dev/md0

$ uname -r

And ofcourse, it is not possible to remount ext3 fs and change
journalling mode.
