Actually, I think it's the same bug. You *cannot* just reuse the storage. Doing a "memset()" doesn't improve anything. The basic issue is that if you reuse it, you're buggy. End of story. Why? It's refcounted, and it's out of your hands. Reusing it is wrong - because it might still be used. The fact that you "released" it is immaterial. Others can have refcounts (and through /sys etc, historically really do have them).
