Things are still stable. So I am pretty optimistic. How are you planning
to proceeed?

The first patch is already in your rcu tree and my gut feeling is that
it is the one that fixes the issue but you're the expert here... Though
I think it should be probably fast tracked and marked for stable?

Are you planning on committing the 2nd patch to your tree?
