Subject: [PATCH v2 08/16] perf parse-events: Constify parse_events_add_numeric
Date: Mon, 15 Apr 2024 23:15:24 -0700	[thread overview]
Message-ID: <20240416061533.921723-9-irogers@google.com> (raw)
In-Reply-To: <20240416061533.921723-1-irogers@google.com>

Allow the term list to be const so that other functions can pass const
term lists. Add const as necessary to called functions.
