      The function jbd2_journal_write_metadata_buffer() calls
      jbd_unlock_bh_state(bh_in) too early; this could potentially allow
      another thread to call get_write_access on the buffer head, modify the
      data, and dirty it, and allowing the wrong data to be written into the
      journal.  Fortunately, if we lose this race, the only time this will
      actually cause filesystem corruption is if there is a system crash or
      other unclean shutdown of the system before the next commit can take
