Subject: [PATCH rcu 6/9] torture: Move torture_shuffle() timeouts to hrtimers
Date: Mon, 17 Jul 2023 11:20:39 -0700 [thread overview]
Message-ID: <20230717182042.1098651-6-paulmck@kernel.org> (raw)
In-Reply-To: <bca717ca-a83a-4540-80ec-732c12623d2d@paulmck-laptop>
In order to gain better race coverage, move the CPU-migration timed
waits in torture_shuffle() to torture_hrtimeout_jiffies().
