From 65c1b5b622d09044af3f872240d65e7343f6f83e Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Thu, 27 Oct 2016 12:49:06 +0200 Subject: iothread: release AioContext around aio_poll This is the first step towards having fine-grained critical sections in dataplane threads, which will resolve lock ordering problems between address_space_* functions (which need the BQL when doing MMIO, even after we complete RCU-based dispatch) and the AioContext. Because AioContext does not use contention callbacks anymore, the unit test has to be changed. Previously applied as a0710f7995f914e3044e5899bd8ff6c43c62f916 and then reverted.
