BSD FFS/UFS and earlier file systems could leave you with all sorts of ordering that was not guaranteed - you did get data written within about 30 seconds but no order guarantees and a crash/fsck could give you interesting partial updates .. really interesting. renaming was one fairly safe case as BSD FFS/UFS did rename synchronously for the most part. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
