RHEL added this unused field by an unknown reason, apparently brainlessy backporting some patch from mainstream.
It looks just as harmless waste of memory, but it is worse, as tools like drgn interpret its presence as indicator that kernel works according to rules of that mainstream kernel that patch was borrowed from. The result - drgn becomes useless. It is unreasonable to fix drgn as it will break it for correct kernels. We could delete this unused field. But for now it seems more clever to keep struct binary compatible, only with the field renamed.
