Subject: [PATCH v3 22/23] tests/plugin: allow memory plugin to do both inline and callbacks
Date: Sat, 13 Feb 2021 13:03:24 +0000	[thread overview]
Message-ID: <20210213130325.14781-23-alex.bennee@linaro.org> (raw)
In-Reply-To: <20210213130325.14781-1-alex.bennee@linaro.org>

This is going to be useful for acceptance tests that check both types
are being called the same number of times, especially when icount is
enabled.
