Hi,

yes, it broke tests and not only this test. There is already patch,
but unfortunately not yet in CVS/git...

This commit also introduced using zero target, which is not guaranteed
to be properly initialized there (try to run without dm_zero loaded),
so new patch also uses error target instead for temporary mapping.


Thanks,
Milan
