This Hardware error tracking "thing" is currently in an awkward location—it doesn't belong in RAS and has minimal connection to vmcore info. Following Baoquan's earlier suggestion, I'll refactor this as a standalone driver, which should make the code organization clearer and more maintainable. https://lore.kernel.org/all/aYvi4Y_HNqk_u1-v@fedora/
