Cc to the author and linux-xfs, since it's xfsprogs related.

The line is produced by `$XFS_IO_PROG -c "fiemap -v 0 65k" $file | 
_filter_fiemap`.
0-64k is a hole and 64k-128k is a data extent.
fiemap ioctl always returns *complete* ranges of extents.

You may ask why the ending hole range is not aligned to 128 in 
473.out. Because
fiemap ioctl returns nothing of querying holes. xfs_io does the 
extra
print work for holes.

xfsprogs-dev/io/fiemap.c:
for holes:
 153     if (lstart > llast) {
 154         print_hole(0, 0, 0, cur_extent, lflag, true, llast, 
 lstart);
 155         cur_extent++;
 156         num_printed++;
 157     }

for the ending hole:
  381     if (cur_extent && last_logical < range_end)
  382         print_hole(foff_w, boff_w, tot_w, cur_extent, lflag, 
  !vflag,
  383                BTOBBT(last_logical), BTOBBT(range_end));

And what you want to change is only the filted output.
Without _filter_fiemap:

/mnt/test/fiemap.473: 
|
 EXT: FILE-OFFSET      BLOCK-RANGE      TOTAL FLAGS 
 |
   0: [0..127]:        hole               128 
   |
   1: [128..255]:      26792..26919       128   0x0

[128..255] corresponds to the BLOCK-RANGE of the extent 
26792..26919.

Finally, I found btrfs returns *complete* rangne of extents but xfs/ext4 does not. :-/
