I don't really like the way this weakens the test for XFS. With this
change, the test no longer is checking that unwritten extent
behaviour is correct.

Rather than weakening the test, perhaps it would be better to
execute 252 for XFS only (with the md5sums added), and then
duplicate it to a new test for all filesystems to run with the
weaker result checking that using the new filter function gives us.
With the amount of common code the two tests share, it should be
trivial to do this....

Alrighty, that sounds pretty straight forward, as long as every one is in agreement. I think that would help retain the tests effectiveness. Eric, Josef, what are your thoughts?
