It is also theoretically possible to report UAFs in stores as well. But doing so is a bit of a hassle, as SLUB performs numerous stores to freed memory, which require careful handling (we don't want to report them).

322dad0 implements UAF detection on each load.
Let's see how it goes.

Does this add slowdown (and code) for something we don't want to use?

We've decided to put all UAF bugs into a single bucket in syzkaller anyway, so I'd better revert this improved UAF detection for now (as it costs us some performance).
We can revisit this issue if upstream developers request more precise UAF detection.
