guarantee_online

函数名称：Return in pmask the portion of a cpusets's cpus_allowed that* are online. If none are online, walk up the cpuset hierarchy* until we find one that does have some online cpus.* One way or another, we guarantee to return some non-empty subset

函数原型：static void guarantee_online_cpus(struct cpuset *cs, struct cpumask *pmask)

返回类型：void

参数：

类型	参数	名称
struct cpuset *	cs
struct cpumask *	pmask

当非pumask_intersects - (*src1p & *src2p) != 0*@src1p: the first input*@src2p: the second input 循环

383

cs等于parent_cs(cs)

384

如果此条件成立可能性小(为编译器优化)(!cs)则

392

pumask_copy - *dstp = *srcp*@dstp: the result*@srcp: the input cpumask

393

396

pumask_and - *dstp = *src1p & *src2p*@dstp: the cpumask result*@src1p: the first input*@src2p: the second input* If *@dstp is empty, returns 0, else returns 1
