Looks good. I also perforned a xfs_bmap on the source and destination files to see the portions that were being detected and copied as data.

Enlarge the test coverage of 286 to includes file mapping with repeated hole/unwritten/unwritten_without_data/data intersections.
Those two new sub-tests could help verifying the current seek_data/seek_hole improvements.
Committed to git://oss.sgi.com/xfs/cmds/xfstests.git, master branch.
--Mark.
