Stefan Hajnoczi 5d6e96efb8 blockdev: acquire AioContext in QMP 'transaction' actions ... The transaction QMP command performs operations atomically on a group of drives. This command needs to acquire AioContext in order to work safely when virtio-blk dataplane IOThreads are accessing drives. The transactional nature of the command means that actions are split into prepare, commit, abort, and clean functions. Acquire the AioContext in prepare and don't release it until one of the other functions is called. This prevents the IOThread from running the AioContext before the transaction has completed.
