[PATCH 9/9] util: Avoid using wrong free function

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

 



Since 1e2ae2e31, changes to use the automagic free logic didn't take
into account that one path uses posix_memalign and the other uses
VIR_ALLOC_N - the former requires using VIR_FREE() and not g_free()
to free the memory.
