[ofa-general] hotplug event handle question

[Vladimir Sokolovsky]

Hi Sean,
I have a question about hotplug event:
I want to handle RDMA_CM_EVENT_DEVICE_REMOVAL event in RDS. When I got
this event, I call to rdma_disconnect function in order to modify the QP
to the error state but I got -EINVAL because of the following code in
cma.c:

        if (!cma_comp(id_priv, CMA_CONNECT) &&
            !cma_comp(id_priv, CMA_DISCONNECT))
                return -EINVAL;


while the state is CMA_DEVICE_REMOVAL.

Should I move the QP to the error state in RDS or cma should handle this
state too.

Thanks,
