[Qemu-devel] [PATCH v2 22/22] iotests: Add test for multiple BB on BDS tree |
Date: |
Mon, 9 Feb 2015 13:38:44 -0500 |
This adds a test for having multiple BlockBackends in one BDS tree. In
this case, there is one BB for the protocol BDS and one BB for the
format BDS in a simple two-BDS tree (with the protocol BDS and BB added
first).
When bdrv_close_all() is executed, no cached data from any BDS should be
lost; the protocol BDS may not be closed until the format BDS is closed.
Otherwise, metadata updates may be lost.
