No, kmemcheck (and kmemleak) was always disabled. It's likely that's possible to trigger allocation failures with slab, I just haven't been successful at it. Lack of good testcase is really problem here -- even if I can't trigger failures I can never be sure that these wont appear in some strange moment. BTW I'll test your patches (from another thread) shortly.
