xfs_io_opt was an option passed to _test_generic_punch used for "-F", as in:

_test_generic_punch -k falloc fpunch fpunch fiemap _filter_hole_fiemap $testfile -F

-F is no longer needed, so I just dropped the whole thing.

I'm sorry this patch has required so much work.  :(

If you simply replace "$xfs_io_opt " with "" in this patch, it applies
again with some fuzz.  i.e. in vim I just did:  

:%s/$xfs_io_opt //g

to fix up the patch itself.

There is also still one instance of "-F" in the context of the hunk
in tests/generic/255 as well which causes a little fuzz.]

Thank you for your perseverance on this patch.  :)
