Subject: [PATCH v4 08/29] selftests/resctrl: Mark get_cache_size() cache_type const
Date: Fri, 15 Dec 2023 17:04:54 +0200 [thread overview]
Message-ID: <20231215150515.36983-9-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20231215150515.36983-1-ilpo.jarvinen@linux.intel.com>
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.
