2016-04-15qemu-iotests: tests: do not set unused tmp variableSascha Silbe
The previous commit removed the last usage of ${tmp} inside the tests themselves; the only remaining users are sourced by check. So we can now drop this variable from the tests.

2016-02-02iotests: Add test for multiple BB on BDS treeMax Reitz
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.
