Subject: [PATCH v2 04/16] perf jevents: Remove the type/version variables
Date: Thu, 28 Jul 2022 15:28:23 -0700	[thread overview]
Message-ID: <20220728222835.3254224-5-irogers@google.com> (raw)
In-Reply-To: <20220728222835.3254224-1-irogers@google.com>

pmu_events_map has a type variable that is always initialized to "core"
and a version variable that is never read. Remove these from the API as
it is straightforward to add them back when necessary.
