    Subject[PATCH tip/core/rcu 0/2] rcu: further grace-period processing cleanups
    This patch set provides a couple of additional grace-period-processing

    1. Propagate ->completed through the rcu_node hierarchy
    when RCU goes idle to prevent an additional needless
    grace period from being started.

    2. Make force_quiescent_state() take a snapshot of ->gpnum-1
    rather than ->completed for consistency with rcu_sched_qs()
    and friends.
