    rcu: Make ->cpu_no_qs be a union for aggregate OR · 5b74c458
    Paul E. McKenney 提交于
    This commit converts the rcu_data structure's ->cpu_no_qs field
    to a union.  The bytewise side of this union allows individual access
    to indications as to whether this CPU needs to find a quiescent state
    for a normal (.norm) and/or expedited (.exp) grace period.  The setwise
    side of the union allows testing whether or not a quiescent state is
    needed at all, for either type of grace period.
    
    For now, only .norm is used.  A later commit will introduce the expedited
    usage.
