Subject: [PATCH 03/10] maple_tree: Remove __must_hold() which does not work
Date: Mon, 15 May 2023 21:17:50 +0800	[thread overview]
Message-ID: <20230515131757.60035-4-zhangpeng.00@bytedance.com> (raw)
In-Reply-To: <20230515131757.60035-1-zhangpeng.00@bytedance.com>

The arguments to __must_hold() seem to be wrong so they should not work,
remove them.
