It's all down to ext3_writepage() using data-journaling rather than
metadata journaling.

The obvious fix is just to make the journal_dirty_async_data() code
commit its writes as metadata if the inode is marked for
data-journaling, and to set the transaction handle to be synchronous in
that case. Sounds like a recipe for deadlock if done incorrectly,
though, so I'll give it a more careful look tomorrow.
