Subject: [PATCH tip/core/rcu 2/4] rcutorture: Make TREE03 use real-time tree.use_softirq setting
Date: Tue, 19 Jan 2021 20:32:34 -0800 [thread overview]
Message-ID: <20210120043236.7254-2-paulmck@kernel.org> (raw)
In-Reply-To: <20210120043144.GA7045@paulmck-ThinkPad-P72>
From: "Paul E. McKenney" <paulmck@kernel.org>
TREE03 tests RCU priority boosting, which is a real-time feature.
It would also be good if it tested something closer to what is
actually used by the real-time folks. This commit therefore adds
tree.use_softirq=0 to the TREE03 kernel boot parameters in TREE03.boot.
