    nvme: split nvme status from block req->errors · 27fa9bc5
    Christoph Hellwig authored
    We want our own clearly defined error field for NVMe passthrough commands,
    and the request errors field is going away in its current form.
    
    Just store the status and result field in the nvme_request field from
    hardirq completion context (using a new helper) and then generate a
    Linux errno for the block layer only when we actually need it.
    
    Because we can't overload the status value with a negative error code
    for cancelled command we now have a flags filed in struct nvme_request
    that contains a bit for this condition.
