名称描述
cpumask_nextpumask_next - get the next cpu in a cpumask*@n: the cpu prior to the place to search (ie. return will be > @n)*@srcp: the cpumask pointer* Returns >= nr_cpu_ids if no further cpus set.
cpumask_next_andpumask_next_and - get the next cpu in *src1p & *src2p*@n: the cpu prior to the place to search (ie. return will be > @n)*@src1p: the first cpumask pointer*@src2p: the second cpumask pointer* Returns >= nr_cpu_ids if no further cpus set in both.
cpumask_any_butpumask_any_but - return a "random" in a cpumask, but not this one.*@mask: the cpumask to search*@cpu: the cpu to ignore.* Often used to find any cpu but smp_processor_id() in a mask.* Returns >= nr_cpu_ids if no cpus set.
