Subject: [PATCH v2 08/14] rcuscale: Rename kfree_rcu() to kfree_rcu_mightsleep()
Date: Wed, 15 Mar 2023 18:18:55 +0000 [thread overview]
Message-ID: <20230315181902.4177819-8-joel@joelfernandes.org> (raw)
In-Reply-To: <20230315181902.4177819-1-joel@joelfernandes.org>
From: "Uladzislau Rezki (Sony)" <urezki@gmail.com>
The kfree_rcu() and kvfree_rcu() macros' single-argument forms are
deprecated. Therefore switch to the new kfree_rcu_mightsleep() and
kvfree_rcu_mightsleep() variants. The goal is to avoid accidental use
of the single-argument forms, which can introduce functionality bugs in
atomic contexts and latency bugs in non-atomic contexts.
