Add per-cgroup local event counters to track RDMA resource limit exhaustion from the perspective of individual cgroups. The rdma.events.local file reports two per-resource counters: - max: number of times this cgroup's limit was the one that blocked an allocation in the subtree - alloc_fail: number of allocation attempts originating from this cgroup that failed due to an ancestor's limit This mirrors the design of pids.events.local, where events are attributed to the cgroup that imposed the limit, not necessarily the cgroup where the allocation was attempted. Also extend rdma.events with a hierarchical alloc_fail counter that tracks allocation failures propagating upward from the requesting cgroup, complementing the existing max counter, so that rdma.events and rdma.events.local share the same output format.
