Patch 1 drops a stale interface-file count from the misc controller documentation. Patch 2 documents the RDMA v1 interface files that are already exposed by the controller and already documented for cgroup v2. Patch 3 notes that the io.latency-specific depth, avg_lat and win io.stat fields are only emitted when blkcg_debug_stats is enabled, and qualifies the usage text that suggests using avg_lat to pick a latency target.
