- * extent that maps all their logical blocks. That's because gfs2.mkfs

- * 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
