Pull RCU fix from Paul McKenney:
 "Fix spurious WARN_ON() for rcu_segcblist_n_cbs() in
  cleanup_srcu_struct()

  This issue was introduced by 78a38cbf6f20 ("srcu: Queue
  sdp->work when the delay timer is successfully deleted")
  during this merge window.

  Enough people are hitting this that I am sending it now
  rather than waiting for the next merge window. Especially
  given that it is a simple one-liner"
