This patch fixes bug 510067 on launchpad.
This patch enables the compile time option CONFIG_EXT3_DEFAULTS_TO_ORDERED
to ensure the data=ordered mode for an ext3 fs mount. This prevents a security 
threat of older data being inadvertently exposed, that arises from mounting the
ext3 fs with the data=writeback mode.

Do consider merging this for Lucid.

Subject: [PATCH] UBUNTU: [Lucid] [Config] ext3 defaults to ordered mode

BugLink: http://bugs.launchpad.net/bugs/510067
Ignore: yes

To prevent a security threat of older data being inadvertently exposed, the
default mount option of ext3 should be ordered instead of writeback. This
patch enables the compile time option CONFIG_EXT3_DEFAULTS_TO_ORDERED to
ensure that an ext3 fs mounts with the data=ordered mode.
