Subject: [RFC PATCH 02/10] perf tests: add test for workqueue
Date: Tue, 13 Jul 2021 14:11:13 +0200	[thread overview]
Message-ID: <333e2e3986d32cf8894105f149abb543a84ec91c.1626177381.git.rickyman7@gmail.com> (raw)
In-Reply-To: <cover.1626177381.git.rickyman7@gmail.com>

It will have subtests testing threadpool and workqueue separately.
This patch only introduces the first subtest, checking that the
threadpool is correctly created and destructed.
This test will be expanded when new functions are added in next
patches.
