From: Max Reitz Date: Thu, 25 Jul 2019 15:55:12 +0000 (+0200) Subject: vpc: Do not return RAW from block_status X-Git-Tag: v4.2.0-rc0~227^2~2 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fbc8e1b7e49dee9b137c1037dc72d8e6fd4aba3d;p=thirdparty%2Fqemu.git vpc: Do not return RAW from block_status vpc is not really a passthrough driver, even when using the fixed subformat (where host and guest offsets are equal). It should handle preallocation like all other drivers do, namely by returning DATA | RECURSE instead of RAW. There is no tangible difference but the fact that bdrv_is_allocated() no longer falls through to the protocol layer.
