Subject: [PATCH v2 3/5] tree/nocb: Adjust RCU_NOCB_WAKE_* macros from weaker to stronger
Date: Sat, 29 Jul 2023 14:27:33 +0000 [thread overview]
Message-ID: <20230729142738.222208-4-joel@joelfernandes.org> (raw)
In-Reply-To: <20230729142738.222208-1-joel@joelfernandes.org>
This is needed to make the next patch work correctly as we rely on the
strength of the wakeup when comparing deferred-wakeup types across
different CPUs.
