sched_debug

Name:This itererator needs some explanation.* It returns 1 for the header position.* This means 2 is CPU 0.* In a hotplugged system some CPUs, including CPU 0, may be missing so we have* to use cpumask_* to iterate over the CPUs.

Proto:static void *sched_debug_start(struct seq_file *file, loff_t *offset)

Type:void

Parameter:

Type	Parameter	Name
struct seq_file *	file
loff_t *	offset

768

n = offset

770

If n == 0 Then Return 1

773

n--

775

If n > 0 Then n = pumask_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.

777

Else n = Uniprocessor. Assume all masks are "1".

780

offset = n + 1

782

If n < nr_cpu_ids Then Return n + 2

785

Return NULL
