From 87f68d318222563822b5c6b28192215fc4b4e441 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 7 Jul 2014 15:18:02 +0200 Subject: block: drop aio functions that operate on the main AioContext The main AioContext should be accessed explicitly via qemu_get_aio_context(). Most of the time, using it is not the right thing to do.
