      jbd2: abort when failed to log metadata buffers · 77e841de
      Hidehiro Kawai authored
      If we failed to write metadata buffers to the journal space and
      succeeded to write the commit record, stale data can be written
      back to the filesystem as metadata in the recovery phase.
      
      To avoid this, when we failed to write out metadata buffers,
      abort the journal before writing the commit record.
      
      We can also avoid this kind of corruption by using the journal
      checksum feature because it can detect invalid metadata blocks in the
      journal and avoid them from being replayed.  So we don't need to care
      about asynchronous commit record writeout with a checksum.
