Linus Torvalds ffc766b31e 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.

Pull lockdep capacity limit updates from Tetsuo Handa:
 "syzbot is occasionally reporting that fuzz testing is terminated due
  to hitting upper limits lockdep can track.

  Analysis via /proc/lockdep* did not show any obvious culprits, allow
  tuning tracing capacity constants"
