From 76ef2cf5493a215efc351f48ae7094d6c183fcac Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Thu, 8 May 2014 16:34:58 +0200 Subject: raw-posix: drop raw_get_aio_fd() since it is no longer used virtio-blk data-plane now uses the QEMU block layer for I/O. We do not need raw_get_aio_fd() anymore. It was a layering violation anyway, so let's get rid of it.
