Peter Zijlstra asked us to find bad annotation that blows up the lockdep storage [1][2][3] but we could not find such annotation [4][5], and Peter cannot give us feedback any more [6]. Since we tested this patch on linux-next.git without problems, and keeping this problem unresolved discourages kernel testing which is more painful, I'm sending this patch without forever waiting for response from Peter.
