Well I believe the main user for this is qdisc, which use skb array.

Why not? skb has next and prev pointers at 1st two fields:
struct sk_buff {
union {
struct {
/* These two members must be first. */
struct sk_buff *next;
struct sk_buff *prev;
...
}
so it's just a question of casting to struct plist.
Well, then the casting can only be done in skb_array implementation?
Ok, could be done in ptr ring. But still looks tricky, because of the
different meaning of prev and last.
Thanks
