Subject: [PATCH rcu 12/13] rcutorture: Test SRCU size transitions
Date: Fri, 4 Feb 2022 15:56:00 -0800 [thread overview]
Message-ID: <20220204235601.3438-12-paulmck@kernel.org> (raw)
In-Reply-To: <20220204235558.GA3221@paulmck-ThinkPad-P17-Gen-1>
Thie commit adds kernel boot parameters to the SRCU-N and SRCU-P
rcutorture scenarios to cause SRCU-N to test contention-based resizing
and SRCU-P to test init_srcu_struct()-time resizing. Note that this
also tests never-resizing because the contention-based resizing normally
takes some minutes to make the shift.
Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
