    Subject[PATCH 1/4] jbd: abort when failed to log metadata buffers
    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.
