Re: [PATCH v6 11/12] nvme-rdma: ratelimit the map-failure error message

From: sashiko-bot@kernel.org
Date: 2026-07-26 11:53:25
Also in: linux-pci

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.
