From 0173e21b617d3de1fcfa917e329bb9194ab332a4 Mon Sep 17 00:00:00 2001 From: Peter Xu Date: Thu, 28 Sep 2017 10:59:55 +0800 Subject: [PATCH] iothread: provide helpers for internal use IOThread is a general framework that contains IO loop environment and a real thread behind. It's also good to be used internally inside qemu. Provide some helpers for it to create iothreads to be used internally. Put all the internal used iothreads into the internal object container.
