Subject: [PATCH 01/18] Revert "checkpatch: Error out if deprecated RCU API used"
Date: Fri, 13 Oct 2023 13:58:45 +0200 [thread overview]
Message-ID: <20231013115902.1059735-2-frederic@kernel.org> (raw)
In-Reply-To: <20231013115902.1059735-1-frederic@kernel.org>
From: "Joel Fernandes (Google)" <joel@joelfernandes.org>
The definition for single-argument kfree_rcu() has been removed,
so that any further attempt to use it will result in a build error.
Because of this build error, there is no longer any need for a special
check in checkpatch.pl.
Therefore, revert commit 1eacac3255495be7502d406e2ba5444fb5c3607c.
