From 6f6dc6565e2b65ec8c0cf47622b4f5f1468d194e Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Mon, 17 Oct 2011 12:32:13 +0200 Subject: block: drop redundant bdrv_flush implementation Block drivers now only need to provide either of .bdrv_co_flush, .bdrv_aio_flush() or for legacy drivers .bdrv_flush(). Remove the redundant .bdrv_flush() implementations.
