Subject: [PATCH rcu 8/9] rcu: Remove __read_mostly annotations from rcu_scheduler_active externs
Date: Fri, 4 Feb 2022 15:08:04 -0800 [thread overview]
Message-ID: <20220204230805.4193767-8-paulmck@kernel.org> (raw)
In-Reply-To: <20220204230751.GA4193671@paulmck-ThinkPad-P17-Gen-1>
From: Ingo Molnar <mingo@kernel.org>
Remove the __read_mostly attributes from the rcu_scheduler_active
extern declarations, because these attributes are ignored for
prototypes and we'd have to include the full <linux/cache.h> header
to gain this functionally pointless attribute defined.
