Currently, we tie the struct mctp_dev lifetime to the underlying struct net_device, and hold/put that device as a proxy for a separate mctp_dev refcount. This works because we're not holding any references to the mctp_dev that are different from the netdev lifetime. In a future change we'll break that assumption though, as we'll need to hold mctp_dev references in a workqueue, which might live past the netdev unregister notification. In order to support that, this change introduces a refcount on the mctp_dev, currently taken by the net_device->mctp_ptr reference, and released on netdev unregister events. We can then use this for future references that might outlast the net device. Signed-off-by: Jeremy Kerr <jk@codeconstruct.com.au> Signed-off-by: David S. Miller <davem@davemloft.net> |
