From 5f3aa1ff4781f39e05b9892d58319a09fedc8918 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Thu, 7 Mar 2013 13:41:44 +0100 Subject: [PATCH] main-loop: add qemu_get_aio_context() It is very useful to get the main loop AioContext, which is a static variable in main-loop.c. I'm not sure whether qemu_get_aio_context() will be necessary in the future once devices focus on using their own AioContext instead of the main loop AioContext, but for now it allows us to refactor code to support multiple AioContext while actually passing the main loop AioContext.
