... although I am beginning to wonder if intel_gt_buffer_pool shouldn't just gain a gt backpointer? That would decouple things more instead of tying the implementation with intel_gt implicitly. Not a strong direction though.

Never mind on this point, code already assumes this relationships for instance in node_create().
