类型参数名称
struct sched_domain *sd
struct sched_group *sg
struct cpumask *mask
842  sg_span等于sched_group_span(sg)
843  sdd等于private
847  清空全部CPU信息
850  sibling等于per_cpu_ptr(sd, i)
857  如果非child则继续下一循环
861  如果非pumask_equal - *src1p == *src2p*@src1p: the first input*@src2p: the second input则继续下一循环
864  设置CPU信息
868  WARN_ON_ONCE(pumask_empty - *srcp == 0*@srcp: the cpumask to that all cpus < nr_cpu_ids are clear.)
