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. Signed-off-by: Chao Leng <redacted> --- drivers/nvme/host/nvme.h | 8 ++++++++ 1 file changed, 8 insertions(+)
