    nvme: split nvme_uninit_ctrl into stop and uninit · d09f2b45
    Sagi Grimberg 提交于
    Usually before we teardown the controller we want to:
    1. complete/cancel any ctrl inflight works
    2. remove ctrl namespaces (only for removal though, resets
       shouldn't remove any namespaces).
    
    but we do not want to destroy the controller device as
    we might use it for logging during the teardown stage.
    
    This patch adds nvme_start_ctrl() which queues inflight
    controller works (aen, ns scan, queue start and keep-alive
    if kato is set) and nvme_stop_ctrl() which cancels the works
    namespace removal is left to the callers to handle.
    
    Move nvme_uninit_ctrl after we are done with the
    controller device.
