writes. In addition flush the disk cache on fsync if the sync cached operation didn't sync the log to disk (this requires some additional bookeping in the transaction and log code). If the device doesn't claim to support barriers, the filesystem has an extern log volume or the trial superblock write with barriers enabled failed we disable barriers and print a warning. We should probably fail the mount completely, but that could lead to nasty boot failures for the root filesystem. Not enabled by default yet, needs more destructive testing first.
