函数名称：Ensure topology masks are sane, i.e. there are no conflicts (overlaps) for* any two given CPUs at this (non-NUMA) topology level.

函数原型：static bool topology_span_sane(struct sched_domain_topology_level *tl, const struct cpumask *cpu_map, int cpu)

返回类型：bool

参数：

类型参数名称
struct sched_domain_topology_level *tl
const struct cpumask *cpu_map
intcpu
1892  如果flags按位与SDTL_OVERLAP则返回:true
1902  如果i恒等于cpu则继续下一循环
1910  如果非pumask_equal - *src1p == *src2p*@src1p: the first input*@src2p: the second input且pumask_intersects - (*src1p & *src2p) != 0*@src1p: the first input*@src2p: the second input则返回:false
1915  返回:true
