H A D | iothread.c | 65c1b5b6 Thu Oct 27 10:49:06 GMT 2016 Paolo Bonzini <pbonzini@redhat.com> 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.
