I think the other way to handle the kernel stack reading would be to
simply make the stack freeing be RCU-delayed, and use the RCU list
itself as the stack cache.
That way reading the stack is ok in a RCU context, although you might
end up reading a stack that has been re-used.
Would that work for people?
