Subject: [PATCH 4/4] trace-cruncher: Add tests for sorted events/systems
Date: Tue, 31 Aug 2021 15:53:57 +0300	[thread overview]
Message-ID: <20210831125357.56862-4-y.karadz@gmail.com> (raw)
In-Reply-To: <20210831125357.56862-1-y.karadz@gmail.com>

An optional parameter 'sort' was added to available_event_systems()
and available_system_events(). Here we add the corresponding test
cases.
