名称	描述
c_start
schedstat_start	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.
seq_hlist_next_percpu	seq_hlist_next_percpu - move to the next position of the percpu hlist array@v: pointer to current hlist_node@head: pointer to percpu array of struct hlist_heads@cpu: pointer to cpu "cursor"@pos: start position of sequence
