It seems that the rpc_shutdown_client logic grabs
a clnt->cl_lock lock, and then in the rpc_exit logic it
writes to the task->tk_action.

But, I don't see anything keeping that from racing with
the __rpc_execute() logic, which might also be modifying
the task object without any locks held.

Thanks,
Ben
