Forget that. There's a third case, which is much more likely:

 - Andrew's patch had a ", 1" where it _should_ have had a ", 0".

This should be fairly easy to test: just change every single ", 1" case in 
the patch to ", 0".

The only case that _definitely_ would want ",1" is actually the case that 
already calls page_mkclean() directly: clear_page_dirty_for_io(). So no 
other ", 1" is valid, and that one that needed it already avoided even 
calling the "test_clear_page_dirty()" function, because it did it all by 
hand.

What happens for you in that case?
