-/**
- * map_journal_extents - create a reusable "extent" mapping from all logical
- * blocks to all physical blocks for the given journal.  This will save
- * us time when writing journal blocks.  Most journals will have only one
- * extent that maps all their logical blocks.  That's because gfs2.mkfs
- * arranges the journal blocks sequentially to maximize performance.
- * So the extent would map the first block for the entire file length.
- * However, gfs2_jadd can happen while file activity is happening, so
- * those journals may not be sequential.  Less likely is the case where
- * the users created their own journals by mounting the metafs and
- * laying it out.  But it's still possible.  These journals might have
- * several extents.
- *
- * TODO: This should be done in bigger chunks rather than one block at a time,
- *       but since it's only done at mount time, I'm not worried about the
- *       time it takes.
