[Qemu-devel] [PATCH 07/11] qga: added empty qmp_quest_get_fsinfo functionality. |

From: Olga Krishtal <address@hidden>
We need qmp_quest_get_fsinfo togather with vss-provider, which works with
volumes. The call to this function is implemented via
FindFirst/NextVolumes. Moreover, volumes in Windows OS are filesystem unit,
so it will be more effective to work with them rather with devices.
