Subject: [PATCH v3 2/5] nvme-core: introduce complete failed request
Date: Thu, 21 Jan 2021 15:03:27 +0800 [thread overview]
Message-ID: <20210121070330.19701-3-lengchao@huawei.com> (raw)
In-Reply-To: <20210121070330.19701-1-lengchao@huawei.com>
Work with nvme native multipath, if a path related error occurs when
queue_rq call HBA drive to send request, queue_rq need complete the
request with NVME_SC_HOST_PATH_ERROR, the request will fail over to
retry if needed.
So introduce nvme_complete_failed_req for queue_rq and
nvmf_fail_nonready_command.
