Handlers can inspect this context and modify certain fields (e.g., nr_pages) to adjust reclamation behavior. The design enforces single active handler to avoid conflicts.

Other folks would know a lot better how this should hook into memcg, but given that this is a cgroup feature, this should allow hierarchical delegation. It probably would be a good idea to aling it with the bpf OOM handler support that Roman is working on.

Thanks.
