css_next_child

函数名称：ss_next_child - find the next child of a given css*@pos: the current position (%NULL to initiate traversal)*@parent: css whose children to walk* This function returns the next child of @parent and should be called

函数原型：struct cgroup_subsys_state *css_next_child(struct cgroup_subsys_state *pos, struct cgroup_subsys_state *parent)

返回类型：struct cgroup_subsys_state

参数：

类型	参数	名称
struct cgroup_subsys_state *	pos
struct cgroup_subsys_state *	parent

如果非pos则

遍历RCU(next, & children, sibling)

如果Monotonically increasing unique serial number which defines a* uniform order among all csses. It's guaranteed that all* ->children lists are in the ascending order of ->serial_nr and* used to allow interrupting and resuming iterations.大于Monotonically increasing unique serial number which defines a* uniform order among all csses.
