From b8c835909ea2056151614780b801331eeeae5333 Mon Sep 17 00:00:00 2001 From: Jianfeng Tan Date: Fri, 20 Apr 2018 15:20:12 +0000 Subject: [PATCH 1/1] ipc: fix timeout handling 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.
