From bf0da4df83e8af7ec02e3809f3dd30cc0a42e4bc Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Thu, 11 Apr 2013 17:24:08 +0200 Subject: [PATCH] dataplane/virtio-blk: check exit conditions before aio_poll() Check exit conditions before entering blocking aio_poll(). This is mainly for consistency since it's unlikely that we are stopping in the first event loop iteration.
