If the OS is still alive, everything is ok (but the OS may sync different pages at different times and in any order if you don't fsync specific ranges with special calls). If the whole machine crashes (power issue, kernel panic, ...), what you find on disk can be a mess. |

Is this "can be" determined by the backing filesystem? E.g., would you expect to get a clean result from a log-structured or copy-on-write filesystem?
