It looks to me like Ted is too focused on benchmark numbers to realize the inevitability of allocate-on-commit as an ext4 feature, and furthermore, as a default. Anyone who cares about Linux's reputation for stability must accept that writing metadata ahead of data is simply insane. And if that hurts us in some benchmarks, then so be it. People who don't case about their data can always revert to the unstable behavior which is the default, even with the 2.6.30 patches.

Yer, it's a big problem. What good is metadata if the actual data it is referencing isn't there? All you've got is a broken filesystem when you bring things back up. I can't believe that.

It's strange that we've had all this 'data loss' stuff levelled at XFS over the years as an advantage of ext3 when they're making even more mistakes with ext4 and replicating problems and scenarios XFS has fixed.
