A mapping failure is per-request and, for an unroutable P2P transfer, deterministic: a workload that keeps issuing one turns this into a log line per I/O. Ratelimit it, as nvme's per-I/O error logging (nvme_log_error()) already is. Assisted-by: Claude:claude-fable-5 Signed-off-by: Mykola Marzhan <redacted>
