[PATCH v2 4/7] virbitmaptest: Turn 'TEST_MAP' macro into a helper function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The function will also be reusable in other places of the code by making
the size check optional. For now only test12* is refactored since it
used TEST_MAP directly.
