Subject: [PATCH v3 06/22] perf test: Add helper functions for abstraction.
Date: Wed, 3 Nov 2021 23:41:52 -0700 [thread overview]
Message-ID: <20211104064208.3156807-7-irogers@google.com> (raw)
In-Reply-To: <20211104064208.3156807-1-irogers@google.com>
Abstract certain test features so that they can be refactored in later
changes. No functional change.
