I think we already have __pick_next_entity in kernel/sched/fair.c

static struct sched_entity *__pick_next_entity(struct sched_entity *se)
{
        struct rb_node *next = rb_next(&se->run_node);

        if (!next)
                return NULL;

        return rb_entry(next, struct sched_entity, run_node);
}

I checked in v5.5-rc1, v5.4 and tip/master too. Let me know if you were
referring to a different version of code.

So I modified the only place its called to the newer
__pick_next_entity(cfs_rq, curr); 

But wanted to verify if that's what you had in mind.
