Subject: [PATCH 03/10] rcu: Reorder tree_exp.h after tree_plugin.h
Date: Thu, 28 Mar 2024 15:53:11 +0800	[thread overview]
Message-ID: <20240328075318.83039-4-jiangshanlai@gmail.com> (raw)
In-Reply-To: <20240328075318.83039-1-jiangshanlai@gmail.com>

From: Lai Jiangshan <jiangshan.ljs@antgroup.com>

Enable tree_exp.h using some rcu_preempt macros introduced in
the next patch. The new macros touch core rcu_preempt fields
and are better to be implemented in tree_plugin.h.
