Subject: [PATCH v2 13/14] RDMA/rxe: Rename kfree_rcu() to kvfree_rcu_mightsleep()
Date: Wed, 15 Mar 2023 18:19:00 +0000	[thread overview]
Message-ID: <20230315181902.4177819-13-joel@joelfernandes.org> (raw)
In-Reply-To: <20230315181902.4177819-1-joel@joelfernandes.org>

The k[v]free_rcu() macro's single-argument form is deprecated.
Therefore switch to the new k[v]free_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.

There is no functionality change with this patch.
