> Subject: [PATCH 2/2] ipc: fix timeout not properly handled in async
>
> In original implementation, timeout event for an async request
> will be ignored. As a result, an async request will never
> trigger the action if it cannot receive any reply any more.
>
> We fix this by counting timeout as a processed reply.
