    rcu: Account for rcu_all_qs() in cond_resched() · dc259acc
    Paul E. McKenney 提交于
    If cond_resched() returns false, then it has already invoked
    rcu_all_qs().  This is also invoked (now redundantly) by
    rcu_note_voluntary_context_switch().  This commit therefore changes
    cond_resched_rcu_qs() to invoke rcu_note_voluntary_context_switch_lite()
    instead of rcu_note_voluntary_context_switch() to avoid the redundant
    invocation of rcu_all_qs().
