      ext4, jbd2: Add barriers for file systems with exernal journals · cc3e1bea
      Theodore Ts'o authored
      This is a bit complicated because we are trying to optimize when we
      send barriers to the fs data disk.  We could just throw in an extra
      barrier to the data disk whenever we send a barrier to the journal
      disk, but that's not always strictly necessary.
      
      We only need to send a barrier during a commit when there are data
      blocks which are must be written out due to an inode written in
      ordered mode, or if fsync() depends on the commit to force data blocks
      to disk.  Finally, before we drop transactions from the beginning of
      the journal during a checkpoint operation, we need to guarantee that
      any blocks that were flushed out to the data disk are firmly on the
      rust platter before we drop the transaction from the journal.
      
      Thanks to Oleg Drokin for pointing out this flaw in ext3/ext4.
