Subject: [PATCH rcu 03/18] rcutorture: Make the TREE03 scenario do preemption
Date: Thu, 12 Dec 2024 10:49:42 -0800 [thread overview]
Message-ID: <20241212184957.2127441-3-paulmck@kernel.org> (raw)
In-Reply-To: <62e4d9a4-18ad-49b3-9656-23e17b78033f@paulmck-laptop>
This commit adds the rcutorture.preempt_duration module parameter to
rcutorture's TREE03.boot parameter list in order to better test preemption
of RCU read-side critical sections.
