----------------------------------------------------------------
This is an irregular pull request for sending a lockdep patch.

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.
