51 * For filesystem fs, the offsets of the various blocks of interest
53 * [fs->fs_sblkno] Super-block
54 * [fs->fs_cblkno] Cylinder group block
55 * [fs->fs_iblkno] Inode blocks
56 * [fs->fs_dblkno] Data blocks
57 * The beginning of cylinder group cg in fs, is given by
58 * the ``cgbase(fs, cg)'' macro.
97 * information in the inode, using the ``blksize(fs, ip, lbn)'' macro.
