    Subject[PATCH v2 05/26] selftests/resctrl: Mark get_cache_size() cache_type const
    Date
    get_cache_size() does not modify cache_type so it could be const.

    Mark cache_type const so that const char * can be passed to it. This
    prevents warnings once many of the test parameters are marked const.
