函数名称：pumask_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.

函数原型：int cpumask_next_and(int n, const struct cpumask *src1p, const struct cpumask *src2p)

返回类型：int

参数：

类型参数名称
intn
const struct cpumask *src1p
const struct cpumask *src2p
38  如果n不等于负1则verify cpu argument to cpumask_* operators
40  返回:d_next_and_bit - find the next set bit in both memory regions*@addr1: The first address to base the search on*@addr2: The second address to base the search on*@offset: The bitnumber to start searching at*@size: The bitmap size in bits* Returns the bit
