FWIW, I just added this to my virtual lab which I use as CI tests, and
it immediately found a use-after-free bug in mac80211!

I did note (this is more for kasan-dev@) that the "freed by" is fairly
much useless when using kfree_rcu(), it might be worthwhile to annotate
that somehow, so the stack trace is recorded by kfree_rcu() already,
rather than just showing the RCU callback used for that.
