[Qemu-devel] [PATCH v11 23/25] replay: fix replay shutdown

[Pavel Dovgalyuk <Pavel.Dovgaluk@ispras.ru>]

This patch fixes shutdown of the replay process, which is terminated with
the assert when shutdown event is read from the log.
replay_finish_event reads new data_kind and therefore the value of data_kind
should be preserved to be valid at qemu_system_shutdown_request call.
