++ * bpf_cpumask_op(struct cpumask_op_args *op, int len)
++ *	Description
++ *		A series of cpumask-related operations. Perform different
++ *		operations base on *op*->type. User also need fill other
++ *		*op* field base on *op*->type. *op*->type is one of them
++ *
++ *		**CPUMASK_EMPTY**
++ *			*(op->arg1) == 0 returned.
++ *		**CPUMASK_AND**
++ *			*(op->arg1) = *(op->arg2) & *(op->arg3)
++ *		**CPUMASK_ANDNOT**
++ *			*(op->arg1) = *(op->arg2) & ~*(op->arg3)
++ *		**CPUMASK_SUBSET**
++ *			*(op->arg1) & ~*(op->arg2) == 0 returned
++ *		**CPUMASK_EQUAL**
++ *			*(op->arg1) == *(op->arg2) returned
++ *		**CPUMASK_TEST_CPU**
++ *			test for a cpu *(int)(op->arg1) in *(op->arg2)
++ *			returns 1 if *op*->arg1 is set in *op*->arg2, else returns 0
++ *		**CPUMASK_COPY**
++ *			*(op->arg1) = *(op->arg2), return 0 always
++ *		**CPUMASK_WEIGHT**
++ *			count of bits in *(op->arg1)
++ *		**CPUMASK_NEXT**
++ *			get the next cpu in *(struct cpumask *)(op->arg2)
++ *			*(int *)(op->arg1): the cpu prior to the place to search
++ *		**CPUMASK_NEXT_WRAP**
++ *			helper to implement for_each_cpu_wrap
++ *			@op->arg1: the cpu prior to the place to search
++ *			@op->arg2: the cpumask pointer
++ *			@op->arg3: the start point of the iteration
++ *			@op->arg4: assume @op->arg1 crossing @op->arg3 terminates the iteration
++ *			returns >= nr_cpu_ids on completion
++ *		**CPUMASK_NEXT_AND**
++ *			get the next cpu in *(op->arg1) & *(op->arg2)
++ *		**CPUMASK_CPULIST_PARSE**
++ *			extract a cpumask from a user string of ranges.
++ *			(char *)op->arg1 -> (struct cpumask *)(op->arg2)
++ *			0 on success, or a negative error in case of failure.
++ *	Return
++ *		View above.
