From 657ada52abb85140e56949f522ecec527b256450 Mon Sep 17 00:00:00 2001 From: Leonid Bloch Date: Wed, 26 Sep 2018 19:04:42 +0300 Subject: qcow2: Avoid duplication in setting the refcount cache size The refcount cache size does not need to be set to its minimum value in read_cache_sizes(), as it is set to at least its minimum value in qcow2_update_options_prepare().
