You also need to amend the description of the test, currently it says:
# Test that an incremental send/receive operation will not fail when the
# destination filesystem has compression enabled and the source filesystem
# has a 4K extent at a file offset 0 that is not compressed and that is
# shared.
The '4k' need to be replaced by 'sector sized extent'

It's not visible in this hunk but before we do the send -p there are
also references to an 8k offsset, this needs to be reworded with the
more generic 'sector sized' language

No point in echo'ing the above string given you no longer echo the
checksums.

I think it will be worth it outputting the checksums in the .full log
since if the test is going to fail for someone likely it will be
reproducible for their particular config and so it pays to have the
checksums in the full log.
