Subject: [PATCH v2 04/14] lib/test_vmalloc.c: Rename kvfree_rcu() to kvfree_rcu_mightsleep()
Date: Wed, 15 Mar 2023 18:18:51 +0000	[thread overview]
Message-ID: <20230315181902.4177819-4-joel@joelfernandes.org> (raw)
In-Reply-To: <20230315181902.4177819-1-joel@joelfernandes.org>

From: "Uladzislau Rezki (Sony)" <urezki@gmail.com>

The kvfree_rcu() macro's single-argument form is deprecated.  Therefore
switch to the new kvfree_rcu_mightsleep() variant. 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.
