Yeah, this looks very similar and it should fix the bug as well. In
fact the fix part looks exactly the same, I just also changed the
slab/stack allocation while you changed the atomic/refcount. But these
are unrelated, IIUC. I actually planned to split it into two patches
but David told me it's not necessary and I should send it as it is.

Just nitpicking about your patch, the subject says simplify while I
don't really see any simplification.
Also it does not mention the UAF bug leading to crashes it fixes,
missing the Fixes: and CC: stable tags.

What do we do now?
