Subject: [RFC PATCH v3 05/15] rcutorture: Make TREE04 use CONFIG_RCU_DYNTICKS_TORTURE
Date: Tue, 19 Nov 2024 16:34:52 +0100 [thread overview]
Message-ID: <20241119153502.41361-6-vschneid@redhat.com> (raw)
In-Reply-To: <20241119153502.41361-1-vschneid@redhat.com>
We now have an RCU_EXPERT config for testing small-sized RCU dynticks
counter: CONFIG_RCU_DYNTICKS_TORTURE.
Modify scenario TREE04 to exercise to use this config in order to test a
ridiculously small counter (2 bits).
