int __first_cpu

(

const cpumask_t *

srcp

)

Definition at line 8 of file cpumask.c.

int __next_cpu	(	int	n,
		const cpumask_t *	srcp
	)

Definition at line 14 of file cpumask.c.

int cpumask_any_but	(	const struct cpumask *	mask,
		unsigned int	cpu
	)

cpumask_any_but - return a "random" in a cpumask, but not this one. : the cpumask to search : 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.

Definition at line 55 of file cpumask.c.

int cpumask_next_and	(	int	n,
		const struct cpumask *	src1p,
		const struct cpumask *	src2p
	)

cpumask_next_and - get the next cpu in *src1p & *src2p
: the cpu prior to the place to search (ie. return will be >
) : the first cpumask pointer : the second cpumask pointer

Returns >= nr_cpu_ids if no further cpus set in both.
