    Linus, are you using with data=writeback?

    Those of us, who did (without UPS), will never do it again.

    Propability of non-trivial FS corruption becomes so much bigger.
    I believe from my experience, average number of crashes before
    one loses FS becomes single digit number.

    With data=ordered, it's quite hard.
