 *	Description

 *		Return id of cgroup v2 that is ancestor of cgroup associated

 *		with the *skb* at the *ancestor_level*.  The root cgroup is at

 *		*ancestor_level* zero and each step down the hierarchy

 *		increments the level. If *ancestor_level* == level of cgroup

 *		associated with *skb*, then return value will be same as that

 *		of **bpf_skb_cgroup_id**\ ().

 *

 *		The helper is useful to implement policies based on cgroups

 *		that are upper in hierarchy than immediate cgroup associated

 *		with *skb*.

 *

 *		The format of returned id and helper limitations are same as in

 *		**bpf_skb_cgroup_id**\ ().
