Note that it wasn't just the kfence bits - that was only a symptom of the problem. The real problem is that Andrew apparently doesn't have a KASAN-capable setup right now, so he isn't building what he sends me. linux-next ends up building the end result, of course, but that's the full series, and the smaller sequences don't get any build testing.
