I'm not sure, there's other people here doing the OS stuff - I'm pretty
much ignorant about what "data=writeback" could mean :-D

They knew however that for the data partitions no FS journaling is
needed, and for the WAL partition meta data journaling is enough, so I
guess they tuned ext3 for this.

Cheers,
